Easy way to create the similar menus in SL for different groups:
Open the Menu maintenance screen and select the Group which needs to be replicated.
Click an Action menu and select the Export menu option to export the selected group menu as an XML format for later use.
(Note: Unless you specify another location, the exported file is saved in to your My Documents folder. The default file name is Menu.xml)
Select the similar other group to import the SL Menu.
Click the Action menu and select the Import menu option to import an already exported XML format menu file.
Respond to the System Message 9859 with Yes to overwrite an existing menu; No to append an existing menu
Hope this helps!!!!!!!!
