Trying to change position of nav menu


I need to change the position of the nav menu on mobile. My nav-bar is fixed on bottom and I can’t understand how to make the nav menu open upward.
Please I can’t find the answer everywhere!

Here is my site Read-Only: LINK

Can you share a read only link to your website?

What I was trying to do is no more visible because I solved it manually. It means that I solved the problem by making a menu from 0. I hoped there was a way to do it with Webflow nav menu.

Btw you can see the result at: Fortissimo in the mobile version
