Sub navigation?

[matthewcoxx]

Is sub navigation even possible in NextJS and this or am I missing something? I cannot figure out how to have a menu like this:

Home
--> Subpage
--> Subpage
-->-->SubSubpage
Main Page
Contact Page

I want to be able to track which option is pressed for example if subpage is selected then Home would be highlighted because it is the parent. Is this possible? If so how?

You would need to separate the menu out into its own component like so:

I added parents, hasChildren, and children (list_of Integer) to the theme headermenutype (renamed nestedmenu in my code).
