In the moment the kendo-toobar-dropdownbutton look like an "normal" toolbar-button. The user has no visual indication that the button reveals a drop down list.

Please add a dropdown-arrow like it is present in the split-button to the dropdown-button.

How to reproduce :

- Create a dropdown button with some items

- Open it with your mouse

What happens :

The first button is automatically focussed. Even with mouse use.

Feature request :

Allow to focus on nothing if you use the mouse.

Or allow to select the default focussed item with an input of DropdownButton component. It could accepts no default focus.
