There are 2 menus in the following site:

I am not sure why this theme is being used this way, but it is how the person made their site. I had fixed this issue before and somehow 3 days later the top menu, when you hover for the child pages, it goes under the second navigation menu. (If you hover over the Shewed Designs, you will see what I mean.)
Now, I thought this was a z-index issue. However, I’ve tried.
I must not be seeing it, as this is a simple CSS fix and I asked my friend to not touch the CSS until this issue is fixed.
I checked Google and Stack overflow, applied a couple suggestions, but to no avail, I think I am just a little too close at the moment to the project and missing something so simple it is nearly stupid.
Not sure what order you’re loading your CSS files, but
#catnavhas az-indexof 999, whilst#topnavis never assigned az-indexvalue greater than 5. Since they are both id’d elements, I think the specificity is equal on both, so it becomes an instance of “last rule applied wins.” To test this, you could add an embeddedstyleattribute to the #topnav<ul>element with a z-index rule that is higher, like 9999.HTH.
