I have a custom post type defined like so with taxonomies are standard categories:

// Register Custom Post Type
function custom_post_type() {

$labels = array(
    'name'                  => _x( 'Works', 'Post Type General Name', 'text_domain' ),
    'singular_name'         => _x( 'Work', 'Post Type Singular Name', 'text_domain' ),

I am trying to list all posts within the post type category. So for example I have illustration as a category so all posts with illustration.

    $cat_id = $category->cat_ID; 

    //list all posts by category
    $args = array(
       'post_type' => 'Works', // the post type
       //not sure how to add category id.
    );
// The query
$the_query = new WP_Query( $args );

// The Loop
if ( $the_query->have_posts() ) {
    echo '<h2> List of posts tagged with this tag </h2>';

    echo '<ul>';
    $html_list_items = '';
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        $html_list_items .= '<li>';
        $html_list_items .= '<a href="' . get_permalink() . '">';
        $html_list_items .= get_the_title();

        $html_list_items .= '</li>';
    }
    echo $html_list_items;
    echo '</ul>';

} else {
    // no posts found
}
?>

• category__and (array) – use category id.

  //list all posts by category
