Accessibility
The TreeView is accessible by screen readers and provides full WAI-ARIA support.
WAI-ARIA Support
The TreeView uses the aria-checked, aria-expanded and aria-selected properties on the nested elements depending on the isChecked, isSelected or isExpanded options.
The TreeView uses the tree role.
To move the focus to the current keyboard navigation position, the TreeView utilizes the tabindex approach.
The TreeView also follows the WAI-ARIA best practices for implementing the keyboard navigation for its widget role and is tested against the popular screen readers.
Section 508
The TreeView is compliant with the Section 508 requirements.
