Filters as dropdown menus?

I have recently started working on the CS Cart platform in order to move my stores from Oscommerce/CRE Loaded to this amazing platform. I have a few unclarities and I would likt to ask you to help me.

I would like to have the filters in dropdown menus horizontaly under the category title and subcategories like here, or as multiple columns displayed one next to the other in the same place.

Is there any contribution that I could use in order to obtain what I want?
