/** * @class Ext.ux.form.SelectBox * @extends Ext.form.ComboBox *

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.
