categories and subcat on "post an ad" first step

Hi all

I have build my classipress categories and sub cat on this way :
REGION 1 > bikes/autos/motos/boats/other
REGION 2 > bikes/autos/motos/boats/other
etc..

When members want to post an ad and arrive on firts step, they have 2 field : the price, and cat dropdown menu with all regions (85) and all subcat (85x5).
If I exclude the categories items (regions) because I don't want them to select it and to be sent to classipress default form... they juste have subcats repeated
bikes/autos/motos/boats/other/bikes/autos/motos/boats/other/...x85.

My question is : is it possible to manage an ajax dropdown menu with 2 levels ?
Dropdown 1 : Select a category (REGION 1,REGION 2, etc...)
Dropdown 2 : Select a subcat of the selected category (bikes,autos,...etc)

Thanks....
