Dynamic Navigation In MODX Revolution using Wayfinder
If you are looking to build some dynamic navigation in MODX Revolution you should check out Wayfinder. It’s a great tool to get what you want done. You can find some great links to documentation for wayfinder at http://sottwell.com/articles/wayfinder.html
The (almost) Complete Guide to Creating Menus in MODx Using Wayfinder has been really useful to me and I recommend it.
