Taxonomy Filter with parents and child of select parent dropdown`s On my website i have pet type (dog, cat, rabbit...) those are taxonomies, and every pet type has its own child taxonomies called pet breed. So lets say we selected in first dropdown dog, in second dropdown i want to list dog breeds. 

I have tried with http://drupal.org/project/hierarchical_select but i cant make it work. 

I tried with Views but still my exposed filters doesnt show at all on Preview or in Block...

Any help would be nice. I tried searching but no luck...

http://www.pets4homes.co.uk/ this is what i want to acomplish same thing as that filter they have but just without taht location field.
the hierarchical select module is the correct solution for this purpose, why it does not work with you?   

Setup steps:
1- add the module folder to sites/all/module
2- go to modules page and enable hierarchical select
3- add new field (Term reference) into your content type with (Hierarchical Select) widget type.
