should have a basic component for split button
We don't have a stand-alone split button widget at this point, but only as an integrated part of our toolbar widget: http://demos.telerik.com/kendo-ui/toolbar/index (see the Insert button definition) You can use the toolbar with a single split button as a substitute, if applicable.
mobile split button too
Shawn, you may consider using our button group widget as an alternative at this point, if applicable.
