What is this widget used for?

This widget is commonly used for FAQs, accordions, collapsible panels, and any content that needs to be hidden by default to save space and improve user experience.

How does it work?

The widget uses JavaScript to toggle a CSS class that controls the max-height property, creating a smooth animation effect. The transition is handled entirely with CSS for better performance.

Can it be customized?

Yes! You can easily customize the animation duration, colors, and behavior by modifying the CSS variables and JavaScript functions.

Technical Details

The implementation uses a simple onclick event handler that toggles the 'active' class on the parent container. This class then triggers the CSS transition on the .details element.

Note: The max-height value (500px) should be adjusted based on your maximum expected content height for optimal performance.
