To add a sub-menu, you need to first hide the main menu.
To hide the main menu go to Pages> Manage Pages, and un-check all the boxes next to the pages. Every un-check will hide the tab of the unchecked page until the entire menu will not be visible.
Then, go to Add an Element> Sub-Menu, and add the submenu element.
Clicking Manage Menu will allow you to choose the names of your menu tabs.
It will also allow you to create a drop-down menu by arranging the pages and checking the boxes next to the pages you want to appear as part of the sub-menu.
