Accessibility Support
Out of the box, the Telerik and Kendo UI TileLayout provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.
The TileLayout 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-tilelayout | role=list | Sets list role to the TileLayout wrapper. |
.k-tilelayout-item | role=listitem | Sets listitem role to the TileLayout items. |
aria-labelledby | Associates the focusable item wrapper with the respective header text element (.k-tilelayout-item-header .k-card-title). | |
tabindex=0 | Makes the item wrapper element focusable. | |
aria-keyshortcuts=Enter | Announces Enter as an available key shortcut when the item is focused. | |
aria-dropeffect=execute | Announces that an action, supported by the drop-target (resizing or reordering) will be executed when the item is dropped. | |
aria-grabbed=true/false | The aria-grabbed state indicates an element's 'grabbed' state in a drag-and-drop operation. | |
.k-tilelayout-item-header .k-card-title | id | Unique and deterministic identifier to link the header text element to the focusable wrapper. |
Managing the Focus
The navigation will be enabled by a Navigable parameter, like the Grid. When Navigable is true, all tiles will have a tabindex of 0, and can be accessed through the reglar Tab key navigation.
Keyboard Shortcuts
| Shortcut | Behavior |
|---|---|
Tab | Move focus to the next tile. If focus is on the last tile, focus the next focusable element on the page. |
Shift + Tab | Move focus to the previous tile. If focus is on the first tile, focus the previous focusable element before the TileLayout. |
Enter | Focuses the first focusable element within the tile. Focus is trapped and wrapped within the tile content and follows its natural Tab sequence. |
Escape | Moves focus back to the TileLayout item wrapper when it is on a focusable element within the tile content. |
Shift + Right Arrow | Reorders the focused tile with the next one (if such exists). |
Shift + Left Arrow | Reorders the focused tile with the previous one (if such exists). |
Ctrl/Cmd(Mac) + Right Arrow | Increments the focused tile width with one column (to a maximum of the preset columns count). |
Ctrl/Cmd(Mac) + Left Arrow | Decrements the focused tile width with one column (to a minimum of 1). |
Ctrl/Cmd(Mac) + Down Arrow | Increments the focused item height with one row (to a maximum of the preset rows count if such option exists). |
Ctrl/Cmd(Mac) + Up Arrow | Decrements the focused item height with one row (to a minimum of 1). |
