Description

The Telerik UI for ASP.NET Core DropDownTree comes with an extensive set of API configurations. This demo shows how to utilize some of its functions, such as disabling the control or setting it as read-only, opening and closing it, getting the currently selected item, or selecting another item manually.

You can check the full list of the supported API calls in the ASP.NET Core DropDownTree API reference documentation. The code is available for both the TagHelper and HtmlHelper mode of the component.
