1.1.1.3 How to delete menus
If you would like to delete an entire menu, do the following:

Click Edit
Click the Delete button at the bottom.
A Prompt will appear to confirm the action that you would like to delete the entire menu. This does not affect other menus, just the menu, menu categories and menu items within the menu you have selected.
