I would like to be able to have multi layered filters on Collection pages of products. i.e. on the screenshot below for Stoves, is it possible to add in two more 'Filter By' drop downs next to the current one, each one filtering the results by the product tags and/or the product vendor.
i.e. a visitor can filter the solves by their preferred Vendor, then an addition filter of the results by their preferred Fuel Type and then a final filter of the desired Output?
