I’ve written to Gary at Doobox a few times about this, but no response so far. I think he was away for a while. I’m hoping someone here can suggest a fix so I can proceed with my site development. Look at this page and see what happens when you evoke one of the nav menu drop downs. They go under the buttons inside the Jet stack. http://thriftycabinets.com/pre-assembled/
I don’t have Jet but is there a z-index setting that you can play with (i.e. decrease)? Or on your menu, is there a z-index setting that you could increase?
