The Telerik UI DropDownButton TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI DropDownButton widget.

The DropDownButton combines the functionality of a button with that of a dropdown element. It allows users to click the primary button and open the drop-down popup to choose from a list of additional actions.
