I have a long nav bar at the top of my site. I'd like to add more horizontally but I'm running out of space.

What I'd like to do is simply stack the nav bar vertically, by splitting the nav bar and moving half of the buttons down.

Is that possible? Or must the nav bar be horizontal as more buttons and pages are added.

You may see the lengthy nav bar www.northeastspca.org

Many Thanks
