Plugin search subcategory post

Hi, is there any plugin to display subcategory post’s titles drop-down in dependency on selected category, category would be in second drop-down. Thanks for help

Example: If I select category Cars from drop-down is it possible to display in second drop-down post’s titles Bmw, Fiat, Renault?
