After reviewing many of the posts on this subject I progressed to a certain point but still need a little direction. With the forum’s help I was able to make the secondary menu sticky on desktop. It looks great on Google Chrome but has some spacing issues on Firefox and Safari. That’s probably the easiest fix.
The other issue I’m finding is to make it sticky on mobile and tablet. I’ve reviewed the breakpoints at https://docs.generatepress.com/article/responsive-display/#responsive-breakpoints but haven’t been able to apply it correctly. I’ve included a link in the private window along with credentials.
As always thanks much!
