I got a little problem right here. So I installed the wp_bootstrap_navwalker and it works so far. I got a 3 stage Navigation.
The problem is that the navwalker adds the dropdown-menu class to every single child element. But I need it to be like this (main navigation in the header section): http://www.dotsource.de/
So the third child should not have the dropdown class and should always be visible.
Do you know how I can remove the class attribute from only the third child element?
I tried to google it but I think my problem might be too specific.
