Im building a new site.

I created custom taxonomies linked to custom posts.

I need a widget that make easy for a user in a page to select different taxonomies hierarchical, getting a list of posts.  I don't undestand if you have any widget plugin suitable.

If it's not clear I do a example.

The user in the taxonomy "kind of trees" select "quercus"

in the taxonomy: "kind of play" select "adventure"

When he starst the serarch have to get the lisy of all post "adventure" in the groups "quercus"

Bye

thankyou very much.
