If you are a menu suite administrator, you can use the Navigation Pane Designer to work with menus in the Navigation Pane.
You can delete a menu from your menu suite, whether it is a menu that you created, or one you received from your solution provider.
There is no undo function once you have completed the deletion.
You can choose to hide a menu instead. This will give you extra space in the menu pane area of the Navigation Pane. The menu is only hidden in design view. Any users that you have assigned the menu to will still be able to see it in their own menu suite.
Even though you delete a menu, all of the items in the menu will still be available in the list of menu items when you right-click in the Navigation Pane Designer and click Insert Items....
Click Tools, Navigation Pane Designer.
Right-click the menu button for the menu that you want to delete and then click Delete.
Click Yes to confirm that you want to delete the menu.
