Accessibility Support
Out of the box, the Telerik and Kendo UI Popover provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.
The Popover 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-popover | role=tooltip/dialog | Announces the tooltip (no focusable content) or dialog (contains focusable elements) role of the component. |
id | The element needs an id to be associated with the aria-describedby attribute of the trigger element. | |
aria-describedby=.k-popover id | Links the popover trigger/anchor element with its corresponding popover container. | |
.k-popover | aria-labelledby=.k-popover-header id | Links the popover container with the popover header element when there is focusable content. |
aria-describedby=.k-popover-body id | Links the popover container with the popover body element when there is focusable content. | |
.k-popover-header | id | Links the popover container with the popover header element when there is focusable content. |
.k-popover-body | id | Links the popover container with the popover body element when there is focusable content. |
Managing the Focus
When the Popover does not contain focusable elements, it is not focusable and acts as a Tooltip component. When the Popover contains focusable elements, and gets opened, the first focusable element within the Popover content is focused. Focus is trapped and wrapped in the Popover content. Upon closing the Popover through the keyboard or by interacting with an element within the Popover content, focus is returned back to the anchor element.
