    $output = '<div id="more-from-cat"><h3>' . $title . '</h3>';
    // The arguments of the post list!
    $args = array(
        // It should be in the first category of our post:
        'category__in' => array( $first_cat ),
        // Our post should NOT be in the list:
        'post__not_in' => array( $post->ID ),
        // ...And it should fetch 5 posts - you can change this number if you like:
        'posts_per_page' => 5
    );
    // The get_posts() function
    $posts = get_posts( $args );
    if( $posts ) {
        $output .= '<ul>';
        // Let's start the loop!
        foreach( $posts as $post ) {
            setup_postdata( $post );
            $post_title = get_the_title();
            $permalink = get_permalink();
            $output .= '<li><a href="' . $permalink . '" title="' . esc_attr( $post_title ) . '">' . $post_title . '</a></li>';
        }
