If you are a menu suite administrator, you can use the Navigation Pane Designer to assign menus to users.
You can only assign a whole menu to a user - not a menu group or a menu item.
Right-click the menu button of the menu that you want to assign to one or more users and then click Assign Users....
In the Assign Users window, in the Assign field, place a check mark next to the name of each user that you want to assign the menu to. To assign a menu to all users, click Assign All.
Click OK.
Repeat the procedure for each of the menus that you want to apply to one or more users.
If the menu is disabled, you must enable it, to make it available to the users. The users will not be able to see it until they refresh the Navigation Pane.
