I'm not sure if I'm posting in the right topic, but here I think this is the most suitable one.

I'm looking for an extension that's able to list all the input I made on alphabet. Here's an example: http://www.xbox360achievements.org/games.php?type=Retail

I want a bar on top with a-z+0-9 so people can select the beginning character of a car (in my case) and get all the cars which start with that particular character. So when they click on "M" they get all the Mazda's, Mercedes, etc.

When they select a car I want them to be able to see the stats etc.

Best for the backend would be an option where I can fill in the "itemname" and the value. So for example "HorsePower" "280".

Does anybody know of such an extension???
