Hi Andrew!
After a few hours of thinking, I found a solution. 🙂
Often, simple ideas are the best ideas => I have simplified my menu structure.
Now it fits without having a second menu on top of the header.
I feared it.
Its such a beautiful theme, but unfortunately I am a coding-noob. 🙂
Thanks a lot for your support!
Hm….good point…..
Yes, I need full responsive theme support.
