I want to create a filter with multiple category or tags..i don't know how to do that in wordpress

I am trying to create a filter in my custom post type- I have created a custom post type with the name of ourrecipes.. you can check the code below for custom post type- function ourrecipes_posttype() {

register_post_type( 'ourrecipes',
// CPT Options
    array(
        'labels' => array(
            'name' => __( 'Ourrecipes' ),
            'singular_name' => __( 'Ourrecipes' )
        ),
        'public' => true,
        'taxonomies' => array('category','post_tag'),
        'has_archive' => true,
        'rewrite' => array('slug' => 'ourrecipes'),
        'supports' => array( 'title','thumbnail' ,'editor','excerpt','custom-fields','page-attributes')
    )
);
                        }

// Hooking up our function to theme setup add_action( 'init', 'ourrecipes_posttype' );
