I'm redesigning my website. I have four levels in the original website (maybe there will be a fifth one in time). When I started a completely new project, the menu only shows me two levels, even though I have four levels again. I didn't have this problem in the older version of Website X5. Does it have something to do with the variable width of the website depending on the resolution (PC vs mobile). How can I make it so that I can see all levels in the menu and not just the top two? I saved one level on the new website. Thank you.
