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).
- *Menus may contain either {@link Ext.menu.Item menu items}, or general {@link Ext.Component Component}s.
- *To make a contained general {@link Ext.Component Component} line up with other {@link Ext.menu.Item menu items} - * specify iconCls: 'no-icon'. 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.
- *By default, Menus are absolutely positioned, floating Components. By configuring a Menu with - * {@link #floating}:false, a Menu may be used as child of a Container.
