Expand/Collapse Widget Gallery

Explore multiple approaches for implementing accessible expand/collapse interactions on the web. Each widget wraps controlled content inside a container with the details class.

Native <details> Element

Show project summary

This widget uses the built-in <details> and <summary> elements to create an accessible disclosure.

Tip: Use open on <details> for default expanded state.

Custom Toggle Button

Keyboard users can press Space/Enter on the button to toggle the content.

Accordion (Single Panel Open)

Only one section stays open at a time, providing a compact FAQ interaction.
