I need to develop a search form with two differents taxonomy (taxo1,taxo2).
When a user selects in taxo1 la term, the second list has to be shown with inside only corresponding taxonomy terms.
Here is a example: if the user selects term departement in the first taxonomy taxo1 (using a select list), then a second select list (with terms from taxo2) should appear with only towns from the department previuously selected.
I can't do that with Views because filters can not interact.
Can anybody give me a way to do this?
