Accessibility

The MultiSelectTree is accessible by screen readers and provides full WAI-ARIA accessibility support.

WAI-ARIA Support

The MultiSelectTree uses the aria-expanded, aria-selected, aria-disabled, aria-haspopup, aria-checked properties on the nested elements depending on the current state of the component and its options.

The MultiSelectTree uses the listbox role, while the popup TreeView uses the tree role with the roving tabindex navigation strategy. Each item from the popup list has an treeitem role.

The MultiSelectTree also follows the WAI-ARIA best practices for implementing the keyboard navigation for its component role and is tested against the popular screen readers.

Section 508

The MultiSelectTree is compliant with the Section 508 requirements.
