Blazor Wizard Accessibility

The Telerik UI for Blazor Wizard is WCAG 2.1 AAA 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.

Wai-Aria

The Wizard component represents a tablist containing tabs with related tabpanels.

Selector Attribute Usage
.k-step-list role=tablist Indicates the role of the tablist container element.
.k-step role=none The implicit semantics of the li element must be removed.
.k-step-link role=tab Specifies the role for the step links.
aria-controls=.k-wizard-step id Refers to the tabpanel element associated with the tab.
.k-step-disabled>.k-step-link aria-disabled=true A disabled (inactive) tab.
.k-step-current .k-step-link aria-selected Indicates whether the tab control is activated and its associated panel is displayed, or not.
aria-current=true Indicates whether the tab control is activated and its associated panel is displayed, or not.
tabindex=0 Removes the element from the page Tab sequence. Set when a tab is not selected so that only the selected tab is in the page Tab sequence.
.k-step:not(.k-step-current) .k-step-link tabindex=-1 Removes the element from the page Tab sequence. Set when a tab is not selected so that only the selected tab is in the page Tab sequence.
.k-wizard-step role=tabpanel Specifies the role of the element.
aria-label Specifies a label tor the panel. As the Wizard represents a step-by-step process, that is usually the pager text (e.g. "Step 2 of 4")
tabindex=0 Keeps the tabpanel in the page tab sequence.

No aria attributes should be applied to the ProgressBar element as it serves a purely aesthetic purpose.
