add_shortcode( \'faq_page_content\', \'the_dramatist_faq_page_content\');
/**

function the_dramatist_faq_page_content() {
    $terms = get_terms(\'sections\'); // Taxonomy name
    echo \'<ul>\';
    foreach($terms as $term) {
        $posts = get_posts(
            array(
               \'post_type\' => \'questions\', // Post type
               \'tax_query\' => array(
                   array(
                       \'taxonomy\' => \'sections\', // Taxonomy name
                       \'field\' => \'slug\',
                       \'terms\' => $term->slug
                   )
               ),
               \'posts_per_page\' => -1
            )
        );
        echo \'<li>\' . $term->name;
        echo \'<ul>\';
        foreach($posts as $post) {
            echo \'<li><a href="\' . get_permalink( $post->ID ) . \'">\' . $post->post_title . \'</a></li>\';
        }
        echo \'</ul></li>\';
    }
    echo \'</ul>\';
}

希望这有帮助。
