Expand / Collapse Widget Demo

This widget demonstrates a simple expand/collapse area. The content is visible when you expand the panel.

• Accessible toggle with ARIA attributes
• Animated show/hide (simple height transition)
• Independent widget inside an example container

Another demonstration with different content. The same widget structure can be reused for multiple sections.

1. Use cases: FAQs, tips, long-form content
2. Keyboard accessible: Tab to focus the button
3. Continue to expand as needed
