A sub-menu in a sub-menu

Hello, I want a sub-menu in a sub-menu, how can I do it?
For example:
Training

  • Architect
    • Beginner Architect
    • Advanced architect

If you’re using the Studio editor, you can simply nest the items in the structure you outlined. We have some documentation here that goes into more detail - Studio Editor: Adding and Managing New Menus | Help Center | Wix.com

If it’s the Wix Editor, you’ll need to enable the advanced menu option, which we have more info on here - Wix Editor: Managing Advanced Menus | Help Center | Wix.com

I’m using the Studio Editor, but I can’t have a submenu within a submenu—I can only have one level of submenu. If I try to nest a submenu inside another, it just displays below instead.

For example, instead of:

Formations

  • Architect
    -Advanced Architect

I get:

Formations
• Architect
• Advanced Architect
