Accordion

Ply accordion is a stacked set of headers that show or hide a body. Copy accordion in, set multi if several panels may be open, and bind isOpen when you need controlled items. It is for in-page disclosure, not top-level app navigation.

When to use

  • FAQs, long settings groups, and optional details on a single page.
  • When headings should remain visible while bodies collapse.

When not to use

  • Primary navigation — use tabs, sidenav, or routes.
  • One show/hide region — a single disclosure or drawer is lighter.

Install with npx ply-ui-cli add accordion.
