Is there a way to have the menu bar on the Ambition Pro page show submenus for pages that are children of the parent pages listed in the main menu?
Or, is there a plug in that you know of that works with Ambition Pro that allows creation of submenus like I’m describing?
Yes, go to dashboard -> appearance -> menus and create a main menu.
Add list of menus. Drag and drop the menus under it to create a sub menu. View link
