In my site I have the need to make some navigation links conditionally visible based on the user type. I would like to use the out of the box horizontal navigation control where its contents at each level can be controlled with states. i.e I would set a state which indicates what the current user type is and this state would control the visibility of some links within the horizontal navigation control. Is there an easy way to accomplish this? Currently I am using parallel site navigation trees and multiple overlaying horizontal nav widgets to accomplish it, but it is quite a pain.
