As the Navigation addon in SP Page Builder is not very working as a site menu (you need to change the content on eac page builder page if menu structure needs to change, you cannot refer to language versions etcetera) I need to get a mega menu with the option for a mobile burger menu activated for our new site with mostly or only sp pagebuilder pages. The layout of the site will have a (SP Page Builder Slideshow addon) image going all the way to the top of the page, i.e. there is no menu position above the slideshow image, instead the menu should be placed on top of the image (I will be using background opacity for the menu).

Now - I guess that this is something that many want for their webpages, but it does not seem transparent to me how to do this in the best possible way. Is it wise to use a helix ultimate template style with a menu in it (but somehow getting the z-index for the menu to reach above the slideshow addon?) or what would be the logical method that will not cause further headaches?

Thanks, Benjamin
