This is the first example of an expand/collapse widget. Click the header above to toggle this content. The widget uses CSS transitions for smooth animations and JavaScript to handle the toggle functionality.
You can customize the max-height property to accommodate different content lengths. The transition creates a nice sliding effect when expanding or collapsing.
This example demonstrates how the widget can handle lists and other structured content while maintaining the same smooth animation.
The expand/collapse widget is particularly useful for creating accordion-style interfaces, FAQ sections, or any content that needs to be selectively revealed to users. By default, the content is collapsed to save space, and users can expand only the sections they're interested in.
The implementation uses a simple onclick event handler attached to the header element, which toggles a CSS class on the details container. This class controls the max-height and padding properties to create the expand/collapse effect.
You can extend this basic implementation by adding keyboard accessibility, ARIA attributes for screen readers, or more complex animations as needed.
