Reply To: Primary navigation not shown correctly and top navigation also on mobile

[Jerry]

Hello Karim,

1) Top navigation is not showing properly because you have too much links added to it, try make few parent links and add rest as child so you can make more space there.

I see also you have disabled a FontAwesome icons and they are needed to be turned on from next location:
Appearance -> Customize -> General -> Extra -> FontAwesome

2) This is totally normal behaviour for mobile menu, you can try to hide a top link via Additional CSS feature
Appearance -> Customize -> General -> Additional CSS

And you need to add next CSS code there:
.mobile-topnav { display: none; }

Best Regards
