Expand/Collapse Widget Gallery
Explore three accessible patterns for revealing optional content with smooth interactions. Each widget demonstrates a different technique for controlling visibility.
Native <details> Element
Leverages the semantic HTML element for automatic keyboard and screen-reader support, enhanced with modern styling.
How does the native expand/collapse pattern behave?
The <details> element provides built-in accessibility, keyboard interactivity, and state management without additional JavaScript. It is ideal for light-weight disclosure widgets.
- Keyboard friendly: Users can focus the summary and toggle it with the Enter or Space keys.
- ARIA aware: Screen readers announce the state change automatically.
- Progressive enhancement: Browsers that do not support
<details>simply show the content expanded.
Tip: Add the open attribute to start expanded, or remove it to default to the collapsed state.
Button-Controlled Panel
A custom toggle button manages a content region via ARIA attributes, offering more styling flexibility and bespoke transitions.
Accordion with Single-Open Group
This accordion pattern ensures only one answer is expanded at a time by grouping toggle buttons.
