I am using a child theme from Sandbox for my site, http://www.burlingtonbookfestival.com. I'd like to edit some things on the page navigation bar at the top of the screen, but am having some trouble. When I hover over parent pages ("Schedule" and "Special Events"), there are drop-down menus that display child pages AND the child pages of the first child pages. In the case of the "Friday, September 21" child page, its child pages are displayed horizontally instead of vertically, so some if its child pages are hidden.
What I'd like the menu to look like is this: When you hover over a parent page (i.e., "Schedule"), a drop down menu comes down vertically and lists the child pages ("Friday," Saturday," and "Sunday"). Then, when you hover over those child pages, their child pages show up in a drop-down menu listed vertically (i.e., when you hover over "Friday," a drop-down menu will show up listing "Opening Celebration," "Readings and Presentations," and "Ongoing Events").
This site, which is also a Sandbox child theme, has a nav bar that does what I want mine to do: http://lorelleteaches.com/.
Is there any way to edit my nav bar to do this, or do I have to create a new list? And do I have to use .css or .php? I haven't worked much with .php, so I'm a little weary about changing those files.
