Expand/Collapse Widget Examples

An expand/collapse widget is an interactive component that allows users to show or hide content on demand. It helps keep interfaces clean and organized by revealing information only when needed.

This pattern is commonly used for FAQs, navigation menus, and content-heavy pages where space management is important.

Accessible widgets ensure that all users, including those using assistive technologies like screen readers, can interact with your content effectively.

• Proper ARIA attributes communicate state to assistive technologies
• Keyboard navigation allows users to operate without a mouse
• Clear visual indicators help all users understand interaction states

Implementation involves three key components:

1. HTML Structure: Use semantic elements with proper ARIA attributes
2. CSS Styling: Provide visual feedback for states and smooth transitions
3. JavaScript: Handle click events and update ARIA attributes dynamically

Always test with keyboard navigation and screen readers to ensure full accessibility.
