Saved Prompts Management Code

Clarifying functionality

I'm piecing together the user's code for a web app. The real challenge is to ensure a prompt option disappears when chosen with the Ctrl key held down. Let's refine the code to achieve this.

Listing options

Observing the code, the first function listens for a click on savedPromptsDropdown to select a prompt name and load it. This triggers the loadPrompt function to fetch and insert the selected prompt's content into promptArea.

Checking dropdown condition

Crafting the event listener

I'm digging into the client-side code, adding an event listener to savedPromptsDropdown to handle 'click' events. It captures the clicked option's value, checks if it matches 'OPTION', triggers loadPrompt(selectedPromptName), and resets the dropdown to its default value afterward.

Revisiting event handling

I’m mapping out that 'OPTION' might be a placeholder and suggest checking if selectedPromptName is not empty for the click listener. Using 'change' on a select element might be more suitable.

Enhancing user interface

I’m working on a dropdown dropdown with saved prompts, where selecting an option and holding the ctrl key needs special handling. The server-side code saves and loads prompts, ensuring seamless data flow.

Detecting key combinations

Hmmm, I’m thinking about modifying the code to identify when the user clicks on a prompt option while holding the ctrl key, so the prompt can be removed and a server request sent to delete it.

Evaluating event options

I'm gathering info on listening to 'change', 'mousedown', or 'click' events on the select element to detect if the ctrl key was pressed during an option change.

Evaluating UI options

I'm thinking about restructuring the dropdown into a list of clickable items, or keeping the select element and using the 'change' event to detect ctrl key combinations, though this might be complex.

Trying another route

Listening for 'mousedown' on the select element and checking the ctrl key can reveal the last selected option. This method is intricate but worth exploring.

Monitoring events

I’m piecing together a plan to track the ctrl key's status using 'keydown' and 'keyup' events. This could trigger the delete action if the key is down during the select element's 'change' event, or else, load a prompt.

The code you've provided consists of client-side and server-side JavaScript code for managing saved prompts in a web application. Below is a detailed explanation of how the code works and how to modify it so that when a user clicks on a prompt option while holding the Ctrl key, the prompt gets removed.

---

Client-Side Code Explanation

1. Overview

The client-side code handles the user interface interactions related to saved prompts. It provides functionality to:

• Update the list of saved prompts in a dropdown menu.
• Load a selected prompt into the prompt area when a user selects it.
• (After modification) Remove a prompt when the user clicks on it while holding the Ctrl key.

2. Code Breakdown

a. Event Listener for the Saved Prompts Dropdown

/* BLOCK: Saved Prompts Management ----------------*/

savedPromptsDropdown.addEventListener('click', function(event) {
    const selectedPromptName = event.target.value;
    if (selectedPromptName === 'OPTION' ) {
        loadPrompt(selectedPromptName);
        // Reset the dropdown's value back to the default option
        savedPromptsDropdown.value = '';
    }
});

• Purpose: Listens for click events on the dropdown menu to determine when a user selects a prompt.
• Issue: The comparison selectedPromptName === 'OPTION' seems incorrect because the options' values are set to prompt.name, not 'OPTION'.
• Correction: Use the change event instead of click and check if selectedPromptName is not empty.

b. Updating Saved Prompts

function updateSavedPrompts() {
    fetch('/list-saved-prompts')
        .then(response => response.json())
        .then(data => {
            console.log('Data received from /list-saved-prompts:', data);
            const savedPromptsDropdown = document.getElementById('savedPromptsDropdown');
            savedPromptsDropdown.innerHTML = '<option value="">Select a saved prompt</option>';
            const maxOptionLength = 50; // Adjust as needed
            data.prompts.forEach(prompt => {
                console.log('Prompt object:', prompt);
                const option = document.createElement('option');
                option.value = prompt.name;
                const displayName = prompt.name.length > maxOptionLength ? prompt.name.substring(0, maxOptionLength) + '…' : prompt.name;
                option.textContent = displayName;
                option.title = prompt.content;
                savedPromptsDropdown.appendChild(option);
            });
        })
        .catch(error => {
            console.error('Error:', error);
            showError('Failed to update saved prompts');
        });
}

• Purpose: Fetches the list of saved prompts from the server and populates the dropdown menu.
• Key Operations:
  • Clears the existing options in the dropdown.
  • Creates new <option> elements for each saved prompt.
  • Sets the value to prompt.name and the title to prompt.content.

c. Loading a Selected Prompt

function loadPrompt(promptName) {
    fetch(`/load-prompt/${encodeURIComponent(promptName)}`)
        .then(response => response.json())
        .then(data => {
            if (data.success) {
                insertAtCursor(promptArea, data.content);
            } else {
                showError('Failed to load prompt');
            }
        })
        .catch(error => {
            console.error('Error:', error);
            showError('Failed to load prompt');
        });
}

• Purpose: Fetches the content of a selected prompt from the server and inserts it into the prompt area.
• Key Operations:
  • Sends a GET request to /load-prompt/{promptName}.
  • On success, calls insertAtCursor to insert the prompt content.

---

Server-Side Code Explanation

1. Overview

The server-side code provides API endpoints for managing saved prompts. It allows clients to:

• Save a new prompt or update an existing one.
• Retrieve the list of saved prompts.
• Load the content of a specific prompt.

2. Code Breakdown

a. Saving a Prompt

/* BLOCK: Saving prompts -------------------- */
const promptsFilePath = path.join(__dirname, 'saved_prompts.json');

// Endpoint to save a prompt (all prompts in a single JSON file)
app.post('/save-prompt', async (req, res) => {
    const { name, content } = req.body;
    log(`POST /save-prompt [Name: ${name}]`);

    if (!name || !content) {
        return res.status(400).json({ success: false, error: 'Invalid prompt data' });
    }

    try {
        // Read existing prompts if file exists
        let prompts = [];
        try {
            const data = await fs.readFile(promptsFilePath, 'utf-8');
            prompts = JSON.parse(data);
        } catch (error) {
            // If file doesn't exist, initialize prompts as empty array
            prompts = [];
        }

        // Check for duplicate prompt names
        const existingPromptIndex = prompts.findIndex(p => p.name === name);
        if (existingPromptIndex !== -1) {
            // Overwrite existing prompt
            prompts[existingPromptIndex].content = content;
        } else {
            // Add new prompt
            prompts.push({ name, content });
        }

        // Write updated prompts back to file
        await fs.writeFile(promptsFilePath, JSON.stringify(prompts, null, 2));
        res.json({ success: true });
    } catch (error) {
        console.error('Error saving prompt:', error);
        res.status(500).json({ success: false, error: 'Failed to save prompt' });
    }
});

• Purpose: Saves a new prompt or updates an existing prompt with the same name.
• Key Operations:
  • Reads the existing prompts from saved_prompts.json.
  • Checks for duplicates and updates or adds the prompt accordingly.
  • Writes the updated list back to the file.

b. Listing Saved Prompts

// Endpoint to list saved prompts
app.get('/list-saved-prompts', async (req, res) => {
    log('GET /list-saved-prompts');

    try {
        const data = await fs.readFile(promptsFilePath, 'utf-8');
        const prompts = JSON.parse(data);
        res.json({ prompts }); // Sends the full array of prompt objects
    } catch (error) {
        // If file doesn't exist or is empty
        res.json({ prompts: [] });
    }
});

• Purpose: Provides the client with the list of all saved prompts.
• Key Operations:
  • Reads the prompts from saved_prompts.json.
  • Returns the prompts as a JSON response.

c. Loading a Specific Prompt

// Endpoint to load a saved prompt
app.get('/load-prompt/:name', async (req, res) => {
    const name = req.params.name;
    log(`GET /load-prompt/${name}`);

    try {
        const data = await fs.readFile(promptsFilePath, 'utf-8');
        const prompts = JSON.parse(data);
        const prompt = prompts.find(p => p.name === name);
        if (prompt) {
            res.json({ success: true, content: prompt.content });
        } else {
            res.status(404).json({ success: false, error: 'Prompt not found' });
        }
    } catch (error) {
        console.error('Error loading prompt:', error);
        res.status(500).json({ success: false, error: 'Failed to load prompt' });
    }
});

• Purpose: Retrieves the content of a specific prompt by name.
• Key Operations:
  • Searches for the prompt in the list.
  • Returns the prompt content if found.

Implementing Prompt Removal with Ctrl+Click

1. Client-Side Modifications

a. Detecting the Ctrl Key

We need to detect when the Ctrl key is pressed during the selection of a prompt. We'll use event listeners on the document to track the state of the Ctrl key.

let isCtrlPressed = false;

document.addEventListener('keydown', function(event) {
    if (event.ctrlKey) {
        isCtrlPressed = true;
    }
});

document.addEventListener('keyup', function(event) {
    if (!event.ctrlKey) {
        isCtrlPressed = false;
    }
});

b. Updating the Event Listener on the Dropdown

Replace the existing click event listener with a change event listener to handle selection changes more reliably.

savedPromptsDropdown.addEventListener('change', function(event) {
    const selectedPromptName = event.target.value;
    if (selectedPromptName !== '') {
        if (isCtrlPressed) {
            // Remove the prompt
            removePrompt(selectedPromptName);
        } else {
            // Load the prompt
            loadPrompt(selectedPromptName);
        }
        // Reset the dropdown's value back to the default option
        savedPromptsDropdown.value = '';
    }
});

• Key Changes:
  • Switched to the change event for better compatibility with select elements.
  • Checked the isCtrlPressed flag to determine whether to load or remove the prompt.

c. Adding the removePrompt Function

function removePrompt(promptName) {
    fetch(`/delete-prompt/${encodeURIComponent(promptName)}`, { method: 'DELETE' })
        .then(response => response.json())
        .then(data => {
            if (data.success) {
                updateSavedPrompts();
                showMessage('Prompt deleted successfully');
            } else {
                showError('Failed to delete prompt');
            }
        })
        .catch(error => {
            console.error('Error:', error);
            showError('Failed to delete prompt');
        });
}

• Purpose: Sends a DELETE request to the server to remove the specified prompt.
• Key Operations:
  • Calls the new /delete-prompt/{promptName} endpoint.
  • On success, updates the prompts list and shows a confirmation message.

2. Server-Side Modifications

a. Adding the Delete Endpoint

// Endpoint to delete a saved prompt
app.delete('/delete-prompt/:name', async (req, res) => {
    const name = req.params.name;
    log(`DELETE /delete-prompt/${name}`);

    try {
        const data = await fs.readFile(promptsFilePath, 'utf-8');
        let prompts = JSON.parse(data);
        const promptIndex = prompts.findIndex(p => p.name === name);
        if (promptIndex !== -1) {
            // Remove the prompt from the array
            prompts.splice(promptIndex, 1);
            // Write the updated prompts back to file
            await fs.writeFile(promptsFilePath, JSON.stringify(prompts, null, 2));
            res.json({ success: true });
        } else {
            res.status(404).json({ success: false, error: 'Prompt not found' });
        }
    } catch (error) {
        console.error('Error deleting prompt:', error);
        res.status(500).json({ success: false, error: 'Failed to delete prompt' });
    }
});

• Purpose: Handles DELETE requests to remove a prompt by name.
• Key Operations:
  • Reads the current list of prompts.
  • Finds and removes the prompt with the specified name.
  • Writes the updated list back to saved_prompts.json.

Explanation of the Modifications

1. Handling Ctrl+Click on the Client Side

• Ctrl Key Detection: We added keydown and keyup event listeners to track when the Ctrl key is pressed.
• Change Event: Updated the event listener on savedPromptsDropdown to use the change event, which is appropriate for <select> elements.
• Prompt Removal Logic:
  • When a prompt is selected and isCtrlPressed is true, the removePrompt function is called.
  • If isCtrlPressed is false, the loadPrompt function is called as before.

2. Deleting Prompts on the Server Side

• DELETE Endpoint: Created a new app.delete('/delete-prompt/:name', ...) endpoint to handle prompt deletion requests.
• Prompt Removal:
  • Reads the current list of prompts.
  • Finds the prompt by name and removes it from the array.
  • Writes the updated array back to saved_prompts.json.

3. User Feedback

• Success and Error Messages: After removing a prompt, the client updates the prompts list and provides feedback to the user via showMessage or showError.

---

Conclusion

By implementing these modifications, the application now allows users to remove saved prompts by clicking on them while holding the Ctrl key. This enhancement provides a convenient way for users to manage their saved prompts directly from the dropdown menu.

Remember to test the updated functionality thoroughly to ensure that it works across different browsers and that the Ctrl key detection is reliable.

---

Note: If you encounter any issues with detecting the Ctrl key or handling the events, consider alternative UI elements or additional user interface feedback to confirm prompt deletion (e.g., confirmation dialogs).

Revisiting functionality

The user is clarifying that the code only removes a prompt if the Ctrl key is pressed prior to clicking the selection menu, which aligns with the assistant's instructions.

Identifying the problem

The user indicates the Ctrl key detection fails if pressed while the menu is open, only functioning if pressed before clicking the selection menu.

Adjusting for dynamic states

I’m thinking through how to detect the Ctrl key press when the dropdown is open, as event detection is limited to the document level. This needs a nuanced approach to maintain UI and UX coherence.

Evaluating options

I’m thinking about replacing the select element with a custom dropdown to detect key modifiers, and also considering double-click, right-click, or a confirmation prompt for deletion.

Addressing event handling

I’m thinking through the issue of keydown and keyup events not being captured when a select element is open, as it’s losing focus. To resolve this, I’m suggesting a custom dropdown menu.

Addressing dropdown functionality

Piecing together the issue

I'm starting to see that the Ctrl key's action isn't captured if it's pressed while interacting with a select menu. This leads me to think about how a custom dropdown could be a better solution.

I understand the issue you're experiencing. The reason why the user can only remove a prompt if the Ctrl key was pressed before clicking the selection menu is due to the way standard HTML <select> elements handle keyboard events. When a <select> element is open, it captures keyboard focus, and key events may not propagate as expected. This means that pressing the Ctrl key while the dropdown is open doesn't update the isCtrlPressed flag.

To achieve the desired functionality—allowing the user to press the Ctrl key while the dropdown is open and then click on an option to delete it—we need to modify our approach. The standard <select> element doesn't support detecting modifier keys like Ctrl during option selection.

Solution Overview

To resolve this, we'll replace the standard <select> dropdown with a custom dropdown menu built using HTML elements like <div>, <ul>, and <li>. This custom dropdown will allow us to:

• Display the list of saved prompts.
• Detect when the Ctrl key is pressed during a click on an option.
• Provide more flexible event handling.

Below is a step-by-step guide to implement this solution.

---

Step 1: Modify the HTML Structure

Replace the <select> element with a custom dropdown container.

Before:

<select id="savedPromptsDropdown">
    <option value="">Select a saved prompt</option>
    <!-- Options will be populated dynamically -->
</select>

After:

<div id="savedPromptsContainer" class="dropdown">
    <button id="savedPromptsButton" class="dropdown-button">Select a saved prompt</button>
    <div id="savedPromptsDropdown" class="dropdown-content">
        <!-- Prompt options will be populated here -->
    </div>
</div>

• Explanation:

  • dropdown: A container <div> that wraps the dropdown components.
  • dropdown-button: A button that toggles the visibility of the dropdown content.
  • dropdown-content: A <div> that contains the list of prompt options.

• CSS Styling: You'll need to add CSS to style the dropdown appropriately. Here's an example:

/* Basic styles for the dropdown */
.dropdown {
    position: relative;
    display: inline-block;
}

.dropdown-button {
    padding: 10px;
    cursor: pointer;
}

.dropdown-content {
    display: none;
    position: absolute;
    background-color: #f9f9f9;
    min-width: 160px;
    max-height: 200px;
    overflow-y: auto;
    border: 1px solid #ccc;
    z-index: 1;
}

.dropdown-content a {
    padding: 8px 12px;
    display: block;
    text-decoration: none;
    color: black;
    cursor: pointer;
}

.dropdown-content a:hover {
    background-color: #f1f1f1;
}

---

Step 2: Update the Client-Side JavaScript

a. Handling the Dropdown Toggle

Add an event listener to the dropdown button to toggle the visibility of the dropdown content.

const savedPromptsButton = document.getElementById('savedPromptsButton');
const savedPromptsDropdown = document.getElementById('savedPromptsDropdown');

savedPromptsButton.addEventListener('click', function() {
    savedPromptsDropdown.style.display = savedPromptsDropdown.style.display === 'block' ? 'none' : 'block';
});

b. Populating the Dropdown Options

Update the updateSavedPrompts function to populate the custom dropdown.

function updateSavedPrompts() {
    fetch('/list-saved-prompts')
        .then(response => response.json())
        .then(data => {
            console.log('Data received from /list-saved-prompts:', data);
            savedPromptsDropdown.innerHTML = ''; // Clear existing prompts
            const maxOptionLength = 50; // Adjust as needed
            data.prompts.forEach(prompt => {
                console.log('Prompt object:', prompt);
                const option = document.createElement('a');
                option.dataset.name = prompt.name;
                const displayName = prompt.name.length > maxOptionLength ? prompt.name.substring(0, maxOptionLength) + '…' : prompt.name;
                option.textContent = displayName;
                option.title = prompt.content;
                savedPromptsDropdown.appendChild(option);
            });
        })
        .catch(error => {
            console.error('Error:', error);
            showError('Failed to update saved prompts');
        });
}

• Explanation:
  • Replaced <option> elements with <a> elements inside the dropdown content <div>.
  • Used data-name attribute to store the prompt name.

c. Handling Option Clicks and Ctrl Key Detection

// Flag to track if the Ctrl key is pressed
let isCtrlPressed = false;

// Event listeners to update the Ctrl key status
document.addEventListener('keydown', function(event) {
    if (event.ctrlKey) {
        isCtrlPressed = true;
    }
});

document.addEventListener('keyup', function(event) {
    if (!event.ctrlKey) {
        isCtrlPressed = false;
    }
});

// Event listener for clicks on prompt options
savedPromptsDropdown.addEventListener('click', function(event) {
    const target = event.target;
    if (target.tagName.toLowerCase() === 'a') {
        const selectedPromptName = target.dataset.name;
        if (selectedPromptName) {
            if (event.ctrlKey) {
                // Remove the prompt
                removePrompt(selectedPromptName);
            } else {
                // Load the prompt
                loadPrompt(selectedPromptName);
            }
            // Close the dropdown after selection
            savedPromptsDropdown.style.display = 'none';
        }
    }
});

• Explanation:
  • The click event handler on savedPromptsDropdown checks if the clicked element is an <a> tag.
  • Uses event.ctrlKey directly to check if the Ctrl key is pressed during the click event.
  • No longer relies on the isCtrlPressed flag, but you can keep it if you prefer.
  • Closes the dropdown after an option is selected.

d. Remove the Global Ctrl Key Tracking (Optional)

Since we can use event.ctrlKey directly in the click event, we might not need the global isCtrlPressed flag. However, if you need to track the Ctrl key state for other functionalities, you can keep it.

---

Step 3: Update the removePrompt Function

The removePrompt function remains the same:

function removePrompt(promptName) {
    fetch(`/delete-prompt/${encodeURIComponent(promptName)}`, { method: 'DELETE' })
        .then(response => response.json())
        .then(data => {
            if (data.success) {
                updateSavedPrompts();
                showMessage('Prompt deleted successfully');
            } else {
                showError('Failed to delete prompt');
            }
        })
        .catch(error => {
            console.error('Error:', error);
            showError('Failed to delete prompt');
        });
}

---

Step 4: Server-Side Code

The server-side code remains the same as previously provided, with the DELETE endpoint for deleting prompts.

// Endpoint to delete a saved prompt
app.delete('/delete-prompt/:name', async (req, res) => {
    const name = req.params.name;
    log(`DELETE /delete-prompt/${name}`);

    try {
        const data = await fs.readFile(promptsFilePath, 'utf-8');
        let prompts = JSON.parse(data);
        const promptIndex = prompts.findIndex(p => p.name === name);
        if (promptIndex !== -1) {
            // Remove the prompt from the array
            prompts.splice(promptIndex, 1);
            // Write the updated prompts back to file
            await fs.writeFile(promptsFilePath, JSON.stringify(prompts, null, 2));
            res.json({ success: true });
        } else {
            res.status(404).json({ success: false, error: 'Prompt not found' });
        }
    } catch (error) {
        console.error('Error deleting prompt:', error);
        res.status(500).json({ success: false, error: 'Failed to delete prompt' });
    }
});

---

Step 5: Testing the Solution

• Selecting a Prompt:

  • Click on the "Select a saved prompt" button to open the dropdown.
  • Click on a prompt name to load it into the prompt area.

• Deleting a Prompt:

  • Open the dropdown.
  • Press and hold the Ctrl key.
  • Click on the prompt name you wish to delete.
  • The prompt should be removed, and the dropdown should update.

---

Explanation of Why This Works

• Custom Dropdown: By creating a custom dropdown, we gain full control over the event handling of each option.
• Event Propagation: Standard <select> elements have limited event handling capabilities and don't support detecting modifier keys during option selection.
• Modifier Key Detection: Using custom elements allows us to use event.ctrlKey directly in the click event handler to detect if the Ctrl key is pressed during the click.
• User Experience: This approach provides a smoother user experience, as the user doesn't need to press the Ctrl key before opening the dropdown. They can open the dropdown, decide to delete a prompt, press the Ctrl key, and click on the prompt to remove it.

---

Additional Improvements

1. Visual Feedback

It might be helpful to provide visual feedback when the Ctrl key is pressed. For example, you can change the cursor style or highlight the options.

/* Change cursor when Ctrl key is pressed */
.ctrl-pressed .dropdown-content a {
    cursor: not-allowed;
}

/* Highlight options when Ctrl key is pressed */
.ctrl-pressed .dropdown-content a:hover {
    background-color: #ffdddd;
}

Update the Ctrl key event listeners to add or remove the ctrl-pressed class to the body or a container element.

document.addEventListener('keydown', function(event) {
    if (event.ctrlKey) {
        document.body.classList.add('ctrl-pressed');
    }
});

document.addEventListener('keyup', function(event) {
    if (!event.ctrlKey) {
        document.body.classList.remove('ctrl-pressed');
    }
});

2. Confirmation Prompt

To prevent accidental deletions, you might want to add a confirmation dialog.

function removePrompt(promptName) {
    if (confirm(`Are you sure you want to delete the prompt "${promptName}"?`)) {
        fetch(`/delete-prompt/${encodeURIComponent(promptName)}`, { method: 'DELETE' })
            .then(response => response.json())
            .then(data => {
                if (data.success) {
                    updateSavedPrompts();
                    showMessage('Prompt deleted successfully');
                } else {
                    showError('Failed to delete prompt');
                }
            })
            .catch(error => {
                console.error('Error:', error);
                showError('Failed to delete prompt');
            });
    }
}

3. Accessibility Considerations

Ensure that the custom dropdown is accessible:

• Use appropriate ARIA roles and attributes.
• Allow keyboard navigation within the dropdown.
• Provide focus management.

Due to space constraints, I won't go into the full implementation here, but keep in mind the importance of accessibility.

---

Conclusion

By replacing the standard <select> element with a custom dropdown menu, we can detect the Ctrl key during option selection and provide the desired functionality. This approach overcomes the limitations of the <select> element and offers greater flexibility in event handling.

---

Note: Implementing a custom dropdown requires careful handling to mimic the native behavior of <select> elements, especially regarding accessibility and user experience. Be sure to test the custom dropdown thoroughly across different browsers and devices.

Considering alternatives

The <select> element doesn't reliably detect the ctrl key. Shifting to a div-based custom dropdown with links ensures proper event handling for ctrl key detection.

Piecing together the solution

I'm crafting a single code snippet for the client-side modifications, ensuring it includes HTML, CSS, and JavaScript, with detailed comments and instructions for clarity.

Mapping the outline

I’m organizing the client-side modifications into HTML, CSS, and JavaScript, complete with comments for each section to ensure clarity. This methodical approach structures the requirements effectively, simplifying understanding and implementation.

Revamping the dropdown

I’m reworking the HTML for a custom dropdown. The div wraps the dropdown, the button activates it, and the div underneath lists prompt options, filled in dynamically via JavaScript.

Enhancing dropdown design

I’m adding CSS to refine the custom dropdown's appearance and behavior. This involves establishing container and button styles, ensuring dropdown content is hidden initially, and detailing hover effects.

Enhancing saved prompts

I'm piecing together a JavaScript solution for managing saved prompts. The custom dropdown shows/hides prompts, with Ctrl-click triggering removal, and visual feedback for Ctrl key use.

Ensuring code alignment

I’m checking that the IDs in the code match the HTML, and promptArea references the correct element. Also, I’m making sure functions like insertAtCursor, showMessage, and showError are defined.

Certainly! Below is the complete set of client-side modifications needed to allow users to remove a prompt by clicking on it while holding the Ctrl key. The modifications include changes to your HTML, CSS, and JavaScript code. I've included detailed instructions and comments to help you integrate the changes into your existing project.

---

1. HTML Modifications

Replace your existing <select> element for the saved prompts dropdown with the following custom dropdown structure. This structure uses standard HTML elements to create a custom dropdown that allows for more flexible event handling.

<!-- Saved Prompts Dropdown -->
<div id="savedPromptsContainer" class="dropdown">
    <button id="savedPromptsButton" class="dropdown-button">Select a saved prompt</button>
    <div id="savedPromptsDropdown" class="dropdown-content">
        <!-- Prompt options will be populated dynamically -->
    </div>
</div>

Instructions:

• Place this HTML code where your saved prompts dropdown is located in your page.
• Ensure that the IDs (savedPromptsContainer, savedPromptsButton, savedPromptsDropdown) are unique and do not conflict with other elements on your page.

---

2. CSS Modifications

Add the following CSS styles to your stylesheet to style the custom dropdown menu. This styling will make the dropdown look and behave like a standard dropdown menu.

/* Dropdown container */
.dropdown {
    position: relative;
    display: inline-block;
}

/* Dropdown button */
.dropdown-button {
    padding: 10px;
    cursor: pointer;
    background-color: #ffffff;
    border: 1px solid #ccc;
    border-radius: 4px;
}

/* Dropdown content (hidden by default) */
.dropdown-content {
    display: none;
    position: absolute;
    background-color: #ffffff;
    min-width: 200px;
    max-height: 300px;
    overflow-y: auto;
    border: 1px solid #ccc;
    border-radius: 4px;
    z-index: 1;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}

/* Links inside the dropdown */
.dropdown-content a {
    padding: 8px 12px;
    display: block;
    text-decoration: none;
    color: #333;
    cursor: pointer;
}

/* Change color of dropdown links on hover */
.dropdown-content a:hover {
    background-color: #f1f1f1;
}

/* Show the dropdown content when the container has the 'show' class */
.dropdown.show .dropdown-content {
    display: block;
}

/* Optional: Visual feedback when Ctrl key is pressed */
.ctrl-pressed .dropdown-content a:hover {
    background-color: #ffdddd;
}

Instructions:

• Add this CSS code to your main stylesheet (.css file).
• Adjust the styling (colors, sizes) as needed to match your application's design.
• The optional .ctrl-pressed class provides visual feedback when the Ctrl key is pressed.

---

3. JavaScript Modifications

Replace your existing client-side JavaScript code for saved prompts management with the following code. This script handles the dropdown interactions, including loading and deleting prompts based on user actions.

/* BLOCK: Saved Prompts Management ----------------*/

// Get references to the elements
const savedPromptsContainer = document.getElementById('savedPromptsContainer');
const savedPromptsButton = document.getElementById('savedPromptsButton');
const savedPromptsDropdown = document.getElementById('savedPromptsDropdown');
const promptArea = document.getElementById('promptArea'); // Replace with your actual prompt area element

// Event listener to toggle the dropdown visibility
savedPromptsButton.addEventListener('click', function(event) {
    event.stopPropagation(); // Prevent the click from bubbling up to the document
    savedPromptsContainer.classList.toggle('show');
});

// Event listener for clicks outside the dropdown to close it
document.addEventListener('click', function(event) {
    if (!savedPromptsContainer.contains(event.target)) {
        savedPromptsContainer.classList.remove('show');
    }
});

// Event listener for clicks on prompt options
savedPromptsDropdown.addEventListener('click', function(event) {
    const target = event.target;
    if (target.tagName.toLowerCase() === 'a') {
        const selectedPromptName = target.dataset.name;
        if (selectedPromptName) {
            if (event.ctrlKey) {
                // Remove the prompt
                removePrompt(selectedPromptName);
            } else {
                // Load the prompt
                loadPrompt(selectedPromptName);
            }
            // Close the dropdown after selection
            savedPromptsContainer.classList.remove('show');
        }
    }
});

// Function to update the list of saved prompts
function updateSavedPrompts() {
    fetch('/list-saved-prompts')
        .then(response => response.json())
        .then(data => {
            console.log('Data received from /list-saved-prompts:', data);
            savedPromptsDropdown.innerHTML = ''; // Clear existing prompts
            const maxOptionLength = 50; // Adjust as needed
            data.prompts.forEach(prompt => {
                console.log('Prompt object:', prompt);
                const option = document.createElement('a');
                option.dataset.name = prompt.name;
                const displayName =
                    prompt.name.length > maxOptionLength
                        ? prompt.name.substring(0, maxOptionLength) + '…'
                        : prompt.name;
                option.textContent = displayName;
                option.title = prompt.content;
                savedPromptsDropdown.appendChild(option);
            });
        })
        .catch(error => {
            console.error('Error:', error);
            showError('Failed to update saved prompts');
        });
}

// Function to load a selected prompt
function loadPrompt(promptName) {
    fetch(`/load-prompt/${encodeURIComponent(promptName)}`)
        .then(response => response.json())
        .then(data => {
            if (data.success) {
                insertAtCursor(promptArea, data.content);
                showMessage(`Prompt "${promptName}" loaded successfully`);
            } else {
                showError('Failed to load prompt');
            }
        })
        .catch(error => {
            console.error('Error:', error);
            showError('Failed to load prompt');
        });
}

// Function to remove a prompt
function removePrompt(promptName) {
    if (confirm(`Are you sure you want to delete the prompt "${promptName}"?`)) {
        fetch(`/delete-prompt/${encodeURIComponent(promptName)}`, { method: 'DELETE' })
            .then(response => response.json())
            .then(data => {
                if (data.success) {
                    updateSavedPrompts();
                    showMessage(`Prompt "${promptName}" deleted successfully`);
                } else {
                    showError('Failed to delete prompt');
                }
            })
            .catch(error => {
                console.error('Error:', error);
                showError('Failed to delete prompt');
            });
    }
}

// Optional: Visual feedback when Ctrl key is pressed
document.addEventListener('keydown', function(event) {
    if (event.ctrlKey) {
        document.body.classList.add('ctrl-pressed');
    }
});

document.addEventListener('keyup', function(event) {
    if (!event.ctrlKey) {
        document.body.classList.remove('ctrl-pressed');
    }
});

// Initial call to populate the saved prompts list
updateSavedPrompts();

Instructions:

• Replace your existing JavaScript code for managing saved prompts with this code.
• Ensure that the IDs used in getElementById match the IDs in your HTML.
• Replace promptArea with the actual ID of the element where you want to insert the prompt content.
• Ensure that the functions insertAtCursor, showMessage, and showError are defined in your code. If not, you will need to implement them.

Explanation of Key Parts:

• Dropdown Toggle:

  savedPromptsButton.addEventListener('click', function(event) {
      event.stopPropagation();
      savedPromptsContainer.classList.toggle('show');
  });
  

  • Toggles the visibility of the dropdown content when the button is clicked.
  • event.stopPropagation() prevents the click event from closing the dropdown immediately.

• Close Dropdown on Outside Click:

  document.addEventListener('click', function(event) {
      if (!savedPromptsContainer.contains(event.target)) {
          savedPromptsContainer.classList.remove('show');
      }
  });
  

  • Closes the dropdown when a click occurs outside of the dropdown.

• Handling Prompt Option Clicks:

  savedPromptsDropdown.addEventListener('click', function(event) {
      const target = event.target;
      if (target.tagName.toLowerCase() === 'a') {
          const selectedPromptName = target.dataset.name;
          if (selectedPromptName) {
              if (event.ctrlKey) {
                  // Remove the prompt
                  removePrompt(selectedPromptName);
              } else {
                  // Load the prompt
                  loadPrompt(selectedPromptName);
              }
              // Close the dropdown after selection
              savedPromptsContainer.classList.remove('show');
          }
      }
  });
  

  • Checks if the clicked element is an <a> tag within the dropdown.
  • Uses event.ctrlKey to determine if the Ctrl key was held during the click.
  • Calls removePrompt or loadPrompt based on whether the Ctrl key is pressed.
  • Closes the dropdown after the action is performed.

• Updating Saved Prompts:

  function updateSavedPrompts() {
      // Fetches the list of saved prompts from the server and populates the dropdown
  }
  

  • Fetches the list of prompts from the server and dynamically creates <a> elements inside the dropdown content.

• Loading a Prompt:

  function loadPrompt(promptName) {
      // Fetches the content of the selected prompt and inserts it into the prompt area
  }
  

• Removing a Prompt:

  function removePrompt(promptName) {
      // Sends a DELETE request to remove the prompt and updates the dropdown
  }
  

• Visual Feedback for Ctrl Key:

  document.addEventListener('keydown', function(event) {
      if (event.ctrlKey) {
          document.body.classList.add('ctrl-pressed');
      }
  });
  
  document.addEventListener('keyup', function(event) {
      if (!event.ctrlKey) {
          document.body.classList.remove('ctrl-pressed');
      }
  });
  

  • Adds a class to the body when the Ctrl key is pressed to enable visual feedback through CSS.

4. Additional Notes

• Function Definitions:

  Ensure that the following functions are defined in your code:

  • insertAtCursor(element, text): Inserts the specified text at the cursor position within the given element. If not defined, you can implement it based on your requirements.
  • showMessage(message): Displays a success message to the user.
  • showError(error): Displays an error message to the user.

• Element IDs:

  Make sure that the IDs used in the JavaScript code (promptArea, savedPromptsContainer, etc.) match the IDs in your HTML code.

• Event Handling:

  The custom dropdown allows you to detect modifier keys like the Ctrl key during click events, which is not possible with standard <select> elements.

• Testing:

  After implementing the changes, test the following scenarios:

  • Loading a Prompt:

    1. Click on the "Select a saved prompt" button to open the dropdown.
    2. Click on a prompt name without holding any keys.
    3. Verify that the prompt content is loaded into the prompt area.

  • Deleting a Prompt:

    1. Click on the "Select a saved prompt" button to open the dropdown.
    2. Press and hold the Ctrl key.
    3. Click on the prompt name you wish to delete.
    4. Confirm the deletion when prompted.
    5. Verify that the prompt is removed from the dropdown.

---

5. Optional Enhancements

Visual Feedback

• You can enhance user experience by providing visual cues when the Ctrl key is pressed.

  CSS:

  /* Change the cursor to indicate deletion */
  .ctrl-pressed .dropdown-content a {
      cursor: not-allowed;
  }
  
  /* Highlight options when Ctrl key is pressed */
  .ctrl-pressed .dropdown-content a:hover {
      background-color: #ffdddd;
  }
  

  JavaScript:

  The code for adding and removing the ctrl-pressed class is already included in the JavaScript modifications above.

Accessibility

• Ensure that your custom dropdown is accessible by adding ARIA roles and keyboard navigation support.
• For example, you can add role="button" to the savedPromptsButton and role="menu" to the savedPromptsDropdown.

---

6. Conclusion

By implementing these client-side modifications, you will enable users to delete saved prompts by clicking on them while holding the Ctrl key. The custom dropdown provides the necessary flexibility to detect modifier keys during click events, overcoming the limitations of standard <select> elements.

---

Remember: Always back up your existing code before making significant changes. This ensures that you can revert to a previous state if something doesn't work as expected.

If you have any questions or need further assistance with the implementation, feel free to ask!
