A ptcs-accordion is a vertically stacked list of items. Each item can be expanded or collapsed to reveal the items content. There can be zero expanded items, one, or more than one item expanded at a time, depending on the proeprties.

Each item in a ptcs-accordion is a ptcs-accordion-item. The ptcs-accordion-item has two main parts:

  • The header that contains the header text and an optional trigger icon
  • The panel that contains the content of the item. The panel can contain a sub-accordion, which results in an expandable / collapsible tree structure.

Usage Example

<ptcs-accordion items="[[items]]"></ptcs-accordion>
