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