Hi, Bomi, I was able to get to the navigation section but I am unsure what you mean by adding main menu items. Could you provide a screenshot or video of some sort so I can get a better understanding? Thanks :slightly_smiling_face:

Thank you so much, this worked great! :slightly_smiling_face: Appreciate your help.
