Let's say you have a hotel booking site and wish to give visitors the possibility to select
Italy -> south -> seaside -> hotel
and only (a list of) posts about hotels by the sea in Southern Italy shows up.
Is there such a plugin available?
Each post could have tags to make such a selection possible.
The only manual way I can think of is to sort the posts in categories, but that would only make listings by one category (like "south") possible.
Any hint would be much appreciated.
