Nucleus CMS v3.21
I have a client who has a working site using Nucleus, which was developed/ instantiated by a former employee with whom he is no longer.
He wants to add a "category" which would be a top-level navigation menu item.
We can find how to Create a new category, but not how to make that a top-level nav menu.
We cannot find the admin panel function that would add this to the structure.
