Accessibility Support
Out of the box, the Telerik and Kendo UI RadioButton provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.
The RadioButton is compliant with the Web Content Accessibility Guidelines (WCAG) 2.2 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.
WAI-ARIA
This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any.
| Selector | Attribute | Usage |
|---|---|---|
.k-radio | type=radio | Announces the radio type of the input. |
label for or aria-label or aria-labelledby | The input requires an accessible name that will be assigned to it. | |
checked=checked | Announces the checked state of the radio button. | |
disabled=disabled or aria-disabled=true | The attribute is rendered only when the radio input is disabled. | |
.k-invalid,.ng-invalid | aria-invalid=true | The attribute is rendered only when the radio button is in a form and announces the valid state of the component. |
