Accessibility #

Screen Reader

Accordion header elements have a button role, an aria-label defined using the label property of the menuitem model and aria-controls to define the id of the content section along with aria-expanded for the visibility state.

The content of an accordion panel uses region role, defines an id that matches the aria-controls of the header and aria-labelledby referring to the id of the header.

The tree elements has a tree as the role and each menu item has a treeitem role along with aria-label, aria-selected and aria-expanded attributes. The container element of a treenode has the group role. The aria-setsize, aria-posinset and aria-level attributes are calculated implicitly and added to each treeitem.
