The ExpansionPanel is compliant with the Web Content Accessibility Guidelines (WCAG) 2.2 AA standards and Section 508 requirements, follows the Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA) best practices for implementing the keyboard navigation for its component role, provides options for managing its focus and is tested against the most popular screen readers.
