**ASAP** Add category filters to a page that displays custom post type (wordpress)

I need to add category filters on a page that displays a custom post type. I already have the exact same filters on another page with another post type so you can simply duplicate the existing .js file and php code (with minor modifications) in order to make this work. I am using Wordpress. In other words, I need exactly the same filters as this : [login to view URL] but applied to this page (different post type and categories) : [login to view URL] I need this done as soon as possible. Thanks
