For the mgtvusa site, the drop down menu disappears when it overlaps the clickable picture: https://snipboard.io/kRv5nr.jpg
I also have this issue, not sure how to figure it out just yet. Hopefully someone will chime in :
It looks like a z-index issue. The clickable pictures probably use z-index to bring to the foreground but the menu doesn’t. I’m not sure of the exact fix but you should try adjusting the z-index of the menu.
I emailed the support and they provided me with this solution.
I’ll give that a shot, thanks
