A drawer is an extension of a panel. You can open and close a drawer in the same way that you can show and hide a panel. A drawer can contain all panel objects, including launchers, menus, applets, other panel objects, and other drawers. When you open a drawer, you can use the objects in the same way that you use objects on a panel.
The following figure shows an open drawer that contains two panel objects.

The arrow on the drawer icon indicates that the icon represents a drawer or menu.
You can add, move, and remove objects from drawers in the same way that you add, move, and remove objects from panels.
