Expand/Collapse Widget Demo

This is a short piece of content that becomes visible when expanded. It demonstrates the basic expand/collapse interaction.

Here is a longer block of content to illustrate how a detached content container behaves inside the widget. It can include lists, links, or images.

• First item with extra details
• Second item to show wrapping
• Third item for demonstration

Note: This widget uses a simple ARIA pattern for disclosure controls. The content container has the "details" class as required.

It demonstrates that any HTML inside the details area will appear when expanded.
