You can add the following types of menu to your panels:

    *


              

      Menu Bar: You can access almost
      all of the standard applications, commands, and configuration options from
      the menus in the Menu Bar. It contains the Applications,
      Places, and System menus.

              

      To add a Menu Bar to a panel, right-click
      on any vacant space on the panel. Choose Add to Panel, then
      choose Menu Bar from the Add to Panel dialog.
      See Section 4.3.2 ― Adding an Object to a Panel for more on this.

            
    *

              

      Main Menu: The Main Menu contains the same
              items as the Menu Bar, but organizes them into one menu instead of three.
              It takes up less space on the panels as a result.

              

      To add a Main Menu to a panel, right-click
      on any vacant space on the panel. Choose Add to Panel, then
      choose Main Menu from the Add to Panel dialog.
      See Section 4.3.2 ― Adding an Object to a Panel for more on this.

            
    *

              

      Submenus: You can add a submenu of the Menu Bar
              or Main Menu directly to the panel. For example, you can add the Games
              submenu of the Applications menu to the panel.

              

      To add a submenu to a panel, open the submenu, right-click on a launcher, then choose
      Entire menu ▸ Add this as menu to panel.
