Blazor Splitter Accessibility

The Telerik UI for Blazor Splitter component is WCAG 2.1 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.


Slitter Pane

Selector Attribute Usage
.k-pane role=group Sets the proper role for the Splitter pane that identifies a set of user interface objects that is not intended to be included in the page's summary or table of contents.

Note: The value of the aria-label attribute of the split-bar elements will be provided to their respective preceding pane element through the API.


Selector Attribute Usage
.k-splitbar role=separator Sets the proper role for the Splitter split-bar element.
aria-label An accessible name, with aria-label should be included if there is more than one focusable separator. The value is set through the corresponding SplitterPane API.
.k-splitbar-horizontal aria-orientation=vertical When a splitbar separates two panes horizontally, its aria-orientation must be explicitly set to 'vertical'.

Note: Setting the value-now attribute of the separator element is not applicable, as the Splitter is a complex layout component allowing splitting the content into multiple panes across any number and level of nested Splitters and panes, thus announcing a value would not convey any meaningful information.
