Filter with multi-categories

Hi all,
i wanna know if it's possible to do this :
- I have my items in mutil-categories (activity sector, country, group)
- I have 3 menu links that show list of activity sectors, countried and groups)

if i'm in sectors list et i clic on a specific sector, i have the list of items in that sector everything's fine.

My question is i want to be able to add in the filter a select list containing countries and another select list containing groups so that in the same chosen sector i can filter item in both a specific country and group.

Hope my questions clear. Thanks a lot.

Hello,

why don't you display the 3 filters that you need in category view?

this will be enough, note that in each filter you can configure how it should appear:
e.g. each field filter can be
select (single value filter)
dual select (range filter)
radio (single value filter)
checkboxes (multi-value filter)
multi-select (multi-value filter)
