Make Expandable Dropdown
Overview
This skill wraps selected text in HTML <details> and <summary> tags to create collapsible/expandable sections in MDX files.
When to Use This Skill
Use this skill when:
- User highlights text and asks to make it expandable/collapsible
- User wants to create a dropdown section
- User mentions making content hidden behind a toggle
- User wants to add a
<details>block
How It Works
- Detect the highlighted text from system reminders
- Automatically extract the summary from the first bullet point if the content starts with a list item (e.g.,
- Summary text). If no bullet point is found at the start, ask the user for a summary. - Remove the first bullet from the content (since it's now the summary)
- Wrap the remaining content in
<details>and<summary>tags - Replace the original text with the wrapped version
Summary Extraction Rules
- If the selected text starts with a bullet (e.g.,
- Technical explanation), use that as the summary - Remove the leading bullet marker and any extra whitespace
- If there's nested content after the first bullet, that becomes the expandable content
- Only ask the user for summary text if the selection doesn't start with a bullet point
Example
Before:
- Point one
- Point two
- Point three
After:
<details>
<summary>Click to expand</summary>
- Point one
- Point two
- Point three
</details>
Implementation Notes
- Preserve all formatting and indentation of the wrapped content
- Add blank lines around the content for proper markdown rendering
- The summary text should be concise and descriptive
- Multiple highlighted sections can be converted in sequence
- Where there are multiple levels of nested bullets, only change the top level bullet in the way described above
