BuddyPress.org

Greetings,
I have buddypress groups set up in a hierarchy. World, Country, State, County, City. I would like to have a dependency dropdown list on my front page that would allow users to navigate those options and “go” to the chosen page. Are there any plugins or ideas as to how I would achieve this?

Using Advanced Classifieds and Directory Pro plugin I can create a directory but it gives the results of classifieds with the location tags. Not a particular page. Here is a video of the drop down list I would like. Lower right corner. https://www.youtube.com/watch?v=NyER5sm4iIs

My current system works but is not user friendly. It can be seen here http://www.suroby.com/places/ clicking subdivision opens the directory further. Thanks in advance.
