We are working on our 2.2 conversion from1.9 and I need to change the default behavior of the Navigation block for guests. We have top level categories like Elementary Schools and Secondary Schools, inside each of those top level categories, we created categories for the different schools (about 26) and inside of the school categories we have categories for subject matter or a general, "Find you teacher". When a guest goes to our home page, the Navigation Courses drop down only shows one category - Elementary Schools. We can drill down and see all of the schools and teacher's sites inside of the Elementary category which is great - if you are a parent looking for an Elementary teacher.
In Navigation, if I increase the number of courses to show from 20 to 100, I see no change in the number of categories and courses. If I increase it to 500, I see most of the categories but then IE8 throws a warning about a slow script.
Is there a way to have the Navigation block show guests only the categories and courses (no links to topics)? I looked at the settings in the block and in Navigation but I couldn't find a way to change the behavior for a guest user.
