Accessibility Support
Out of the box, the Telerik and Kendo UI RadioGroup provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.
The RadioGroup 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-list | role=radiogroup | Announces the radiogroup role of the element. |
.k-radio-item | role=none | Due to issues with nested items, forces a no-role state. |
.k-radio | readonly or aria-readonly | The attribute is rendered only when the radio button is read-only. |
aria-invalid=true | The attribute is rendered only when the radio button is in a form HTML element and announces the invalid state of the component. | |
.k-disabled > .k-radio | disabled or aria-disabled | The attribute is rendered only when the radio button is disabled. |
Keyboard Navigation
The group of RadioButtons does not implement any keyboard navigation. Everything is handled through the default browser behavior for radio buttons.
| Shortcut | Behavior |
|---|---|
Up/Left | Moves focus to previous button and selects it. If first button is focused, moves focus to the last. |
Down Arrow or Right Arrow | Moves the focus to the next button and selects it. If the last button is focused, moves the focus to the first one. |
Testing
The RadioGroup has been extensively tested automatically with axe-core and manually with the most popular screen readers.
Screen Readers
The RadioGroup has been tested with the following screen readers and browsers combinations:
| Environment | Tool |
|---|---|
| Firefox | NVDA |
| Chrome | JAWS |
| Microsoft Edge | JAWS |
