Dynamic Dependant DropDown List: US States & Counties

I was googling for a way to show a drop down menu with states that populates another menu with counties from the selected state. I found a nice dynamic dependent drop down script (with categories & subcategories) at dreamwebstore.com. However, adding over 2000 counties in a single JavaScript file is not such a good idea because such a script is quite big (200KB+) and in many cases (a slow internet connection, some downloads in progress etc.) it will take some time to load.

I’ve decided to keep the counties from each state in separate files. For instance, if we select Hawaii state (with 5 counties), only the hi.js file will load which has only a size of 515 bytes. To do this I’ve used the powerful JavaScript library JQuery.
