Provide an option to modify the ComboBox so there is no space between the ComboBox and the dropdown.
We would like to be able to override the behavior of the Clear button in the editable combo box.
When the user has started typing into an editable combo box, and they click the Clear button before they've selected another item, we want to revert their text to what was in there before they started typing and keep the previously selected item selected, rather than clearing the text and selected item.
If you can add that functionality, even better, but it should be enough to just expose the Clear button's Click event (with a Cancel param or another way to ensure the text isn't cleared), so we can override the current functionality.
It would be nice to have the ability to select different item in the dropdown by keyboard up/down arrows.
This feature probably does not make sense on mobile platforms, but it would be great on desktop platforms.
