Description

The Telerik UI for ASP.NET Core MultiSelect provides a built-in Select All functionality through the SelectAll configuration option. When enabled, a sticky header item appears at the top of the dropdown that allows users to select or deselect all items with a single click. Combined with the Checkboxes option, the header displays a checkbox that reflects the aggregate selection state: unchecked, indeterminate, or checked. When filtering is active, the Select All action applies only to the currently visible items.
