Top level Nav – label only

How do I make the top level tabs of the navigation bar be custom links only. (I don’t want them to go to a page but be only a text label. At present a url field (custom link) is only available for the ‘home’ tab, but none of the others. Template: Evolution, version 2.7. I have looked at this tutorial, BUT as mentioned above the url option is not in any of the menu tabs. http://easywpguide.com/wordpress-manual/appearance/updating-the-menu/adding-a-custom-link-menu-item/
