The drop-down element is an object of type MultiColumnComboBoxElement. Use this element to set the drop-down style, animation and sizing as you would do for the regular combo box.
The EditorControl property of the RadMultiColumnComboBoxElement gives you a reference to the RadGridView control. Using that reference you can obtain the RadGridView object and work as with normal RadGridView control. Refer to the RadGridView documentation for additional information on RadGridView.
