/**
 * Makes a ComboBox more closely mimic an HTML SELECT.  Supports clicking and dragging
 * through the list, with item selection occurring when the mouse button is released.
 * When used will automatically set {@link #editable} to false and call {@link Ext.Element#unselectable}
 * on inner elements.  Re-enabling editable after calling this will NOT work.
