| 22 | * A WAI-ARIA friendly accordion component. |
| 23 | * An accordion is a collection of expandable panels associated with a common outer container. Panels consist |
| 24 | * of a header and an associated content region or tabpanel. The primary use of an Accordion is to present multiple sections |
| 25 | * of content on a single page without scrolling, where all of the sections are peers in the application or object hierarchy. |
| 26 | * The general look is similar to a tree where each root tree node is an expandable accordion header. The user navigates |
| 27 | * and makes the contents of each panel visible (or not) by interacting with the Accordion Header |
