I'll try to get something up this weekend. I didn't have the substance in the web site to test what I believe your question is. I assumed that if I chose "Entire Navigation Route" it would highlight every level on the menu through to the current page and if I chose current item, it would only highlight the current item (and not the top level of the menu which held that link.
This could be from testing/previewing the menu when there were no links included. I have seen that in my other menu software, but then it should recognize that the current page is not "#" and none should be highlighted rather than all.
Am I correct about what the choices mean, because that is what I am after?
