How can I make a field dependent filter (chained filter)?

In the project I'm experimenting to do with phprad, I need to make chained category and subcategory filters...
ie: only subcategories related to selected categories are available. Subcategory drop-down is filled with values related to selected category.

I watched the video about filters and tried some things on my own but I couldn't find a way...
Is it possible to do this in phprad?

Thanks in advance.
