Now within the Ubertor system Approved Vendors can add 3rd level navigation. Actually, they could add 3rd level, 4th, 5th, 6th, etc. Not sure if you would need that many levels to your navigation, but either way, the power is there for Approved Vendors to expand your navigation.
Calgary Realtors John Hripko and Josh Nelson have taken advantage of this new functionality and added it to their new Ubertor website. Check out their website, not only have they added a ton of pages to the website but they have utilized the third navigation functionality so that you can dig down into the different condo buildings in different areas.
