 * @class Ext.menu.Menu
 * @extends Ext.Container
 * <p>A menu object.  This is the container to which you may add menu items.  Menu can also serve as a base class
 * when you want a specialized menu based off of another component (like {@link Ext.menu.DateMenu} for example).</p>
 * <p>Menus may contain either {@link Ext.menu.Item menu items}, or general {@link Ext.Component Component}s.</p>
 * <p>To make a contained general {@link Ext.Component Component} line up with other {@link Ext.menu.Item menu items}
 * specify <tt>iconCls: 'no-icon'</tt>.  This reserves a space for an icon, and indents the Component in line
 * with the other menu items.  See {@link Ext.form.ComboBox}.{@link Ext.form.ComboBox#getListParent getListParent}
 * for an example.</p>
 * <p>By default, Menus are absolutely positioned, floating Components. By configuring a Menu with
 * <b><tt>{@link #floating}:false</tt></b>, a Menu may be used as child of a Container.</p>
