Distributor Directory listing?

I am in the research stage of finding a CMS system for a redesign of our client’s site. I have installed and played around with MODx and find it to be a robust and powerful system compared to other solutions that I have used in the past–and would like to switch to MODx. The only feature that I need for this project that I can not find, is the ability to have a directory listing by State/region for their distributors (see link.)

Is the achievable? The formatting will change dramatically, but the basic listing concept will stay the same...click on State’s abbreviation for distributor listing.
Thanks in advance,
Dustin

How many distributors do you expect to have? If under a few hundred, Ditto would work and be manageable. Each distributor could even have it’s own Google Map point live from the pages and so on.

Thanks for the quick reply. Currently there is ~120. I can not imagine it expanding to more than 250 in the foreseeable future. I will download Ditto to my demo install and give it a try. Thanks again
