Accessibility
The Kendo UI for Angular DropDownTree component is WCAG 2.2 AA and Section 508 compliant. The component also follows the WAI-ARIA best practices for implementing the keyboard navigation for its component role, and is tested against the popular screen readers.
Due to the rich feature set of the library and complexity of some components, the specific combination of configuration options may lead to inaccessible component rendering. Perform thorough testing on any modifications applied to the Kendo UI for Angular components to ensure that they continue to comply with the desired level of accessibility standards.
Associating the DropDownTree with kendo-label or kendo-floatinglabel component ensures that the focusable Input element receives the aria-labelledby attribute and complies to the respective accessibility requirement.
The following example demonstrates the accessibility compliance of the DropDownTree component. Open the example in a new window to evaluate it with Axe Core or other accessibility tools.
