Expand/Collapse Widget Examples

This is a basic expand/collapse widget. Click the header to reveal or hide this content. The widget uses CSS transitions for smooth animations and JavaScript to toggle the expanded state.

You can use this pattern for FAQs, accordions, or any collapsible content sections on your website.

This widget supports multiple instances on the same page. Each example is independent and can be expanded or collapsed without affecting others.

The animation uses CSS max-height transitions for smooth expand/collapse effects. The icon rotates to indicate the current state of the widget.

Consider accessibility by adding ARIA attributes for screen readers in production environments.

To implement this widget:

• Wrap each widget in a div with class "example"
• Use a clickable header (h2, h3, etc.) with the onclick handler
• The controlled content should be in a div with class "details"
• Include the CSS for transitions and styling
• Add the JavaScript function for toggle functionality

The max-height value in CSS should be set high enough to accommodate your longest content.
