Hi,
I think I didn’t explain me good.
My question is how to show another menu on mobile version (there is a guide here: http://kriesi.at/documentation/enfold/changing-the-menu-on-mobiles/ but it doesn’t work.)

The post you linked shows how to hide some elements on mobile version, but I want to have another menu.
Let me know.
cheers

Hi,
no it’s not what I’m trying to do.
The position of the navbar is correct.
What is wrong is the movement that the navbar does scrolling the page.
As you can see the navbar first moves down, the comes back to the top of the page.
