Category selection modification for user submission

Hello,

I am currently working on a classified theme that allows users to submit their own classified listing.

In doing so they choose which category they wish for their listing to be displayed within.

I am currently using ( wp_dropdown_categories ) to display a dropdown menu for users to choose their desired category from, which does the job well. However due to the amount of categories the list is too excessive and not very user-friendly.

Categorys list as follows :

Location > Type of item > Make > Age > Size

The ideal would be to produce something similar to the above ebay category selection where you first choose the main category you wish to place your listing and then refine it down to the ultimate category listing.

My question is, is this possible with wordpress? And can anybody help me with the code needed for this task?

Thanks for your time.
