Cirrhoz, you’re welcome.
Shane, I appreciate your suggestion, but I would need to the top level menu to automatically retrieve the top level documents, and so even if I wrote my own script, it would end up trying to copy a lot of Wayfinder’s functions, so I might as well use Wayfinder. I had this problem for the site I’m doing for a client, and I need everything to be as automatic as possible for them. If this was my own site, I’d consider doing it with a custom snippet.

I suppose everything is different for every project, isn’t it?
Nonetheless, thanks for sharing that example!
