Can't Manage To Show The Entire Menu In Responsive

[Demirdiouff]

Hello everybody, 

 

I need your help about a little problem that I can't manage to resolve by myself. 

 

 

 

 

Let me explain: I have a laptop 1920px, considered as "big desktop" in responsive,

Everything's fine in this picture, my last category is "Accessoires" and it's showing fine.

 

But in a smaller screen like a 13xx px this menu doesn't show all in a single line. There is 3 categories which goes under "Technologique" etc.... so it pushes my search bar etc...

 

I can't manage to find the solution, to put everything on the same line, in every size of screens.

 

 

If any of you has a solution for me it would be really nice. I'm been working on it since this morning.

 

 

Thank you,
