- * @class Ext.ux.form.SelectBox
- * @extends Ext.form.ComboBox
- * <p>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.</p>
