Guidance Needed for Recreating Dropdown Menu Structure in Relume

Hey Folks! Relume newbie here.. I'm trying to recreate a dropdown menu such as the one you see in the screenshot. I used mark down prompting with creating the sitemap since I wanted a specific hierarchy and I must say it worked and turned out well. The only thing that is a bit confusing for me now, is that I now have pages where there shouldn't be any. As one can see in the screenshot or directly on the website - idemia.com - the top navbar just opens a drop-down menu, but not another page when one tries to click, with the exception of "Careers" The sitemap I have now seems to open a subpage from every top navbar from where then the other pages can be accessed. I now wonder what happens if I delete that page how this would affect the sitemap, rather if it would affect the sitemap/wireframe correctly. Again, I simply want to recreate the navigation system of the above-mentioned site and would really appreciate your advice/help with this guys. Many thanks in advance!
