Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Accordion | Choose accordion when multiple related page sections can be independently shown or hidden without changing route, page context, or selected mode. | Activating a section header toggles only the panel it owns unless the component is explicitly single-open. | APG documents accordion header button, heading, expanded state, controlled panel, optional region, and keyboard interaction expectations. |
