When I upgraded to 9.3.4 we started having problems with Navigation Menu Items in our header appearing behind our page components.
We are currently on v 9.5.6 and are still experiencing the same issues. I’ve read all of the other related threads pertaining to this issue (some were over a year old) and have tried to resolve the issue with CSS but to no avail.
Specifically, I tried adding the following CSS to both my theme and master page.
.sk-navigation .sk-subnavigation{
z-index: 5000 !important; }
This is really a major pain for my users that we’ve been trying to live with for the past few months. Is anyone else experiencing this issue?
