To add a menu, perform the following steps:
In a file manager window, access the location where you want to add the menu. For example, if you want to add a menu to the Applications menu, enter applications:/// in the field on the location bar.
Choose File -> Create Folder. An untitled folder is added to the view pane. The name of the folder is selected.
Type a name for the folder, then press Return.
The next time that you log out then log in again, the menu is in the assigned location.
