<?php

$taxonomies = get_object_taxonomies( array( 'post_type' => 'faq',) );
 
foreach( $taxonomies as $taxonomy ) :
 
    // Gets every "category" (term) in this taxonomy to get the respective posts
    $terms = get_terms( array( 'taxonomy' => 'faqt', 'parent' => 0, 'hide_empty' => 0, ) );
 
    foreach( $terms as $term ) : ?>
<div>
    <h3><a href='faqt/<? echo $term->slug; ?>'><? echo $term->name; ?></a></h3>
        </div>
 
        <?php
        $args = array(

                'posts_per_page' => -1,
                'tax_query' => array(

                    )
                )
 
            );
        $posts = new WP_Query($args);
 
        if( $posts->have_posts() ): while( $posts->have_posts() ) : $posts->the_post(); ?>
 

    <ul>
        <li><a href="<?php echo get_permalink(); ?>"><?php  echo get_the_title(); ?></a></li>
