How to display term 3 levels in wordpress and without repeats?

Question

WordPress

Good day.
I tried a bunch of different ways but it didn't work out
Given:
You need to display all term 3 nesting levels (which have posts). But that they do not repeat.
Yes:

Code:

<? 
$args = array(  'post_type' => 'novosti',	'taxonomy' => 'brands', );
$args_brands = array(	'orderby' => 'name',	'hide_empty' => 1, 'depth' => 2,);
$categories = get_terms('brands', $args_brands ); if($categories){ foreach ($categories as $cat){ 
$termID = $cat->term_id; 
$taxonomyName = "brands";
$termchildren = get_term_children( $termID, $taxonomyName ); foreach ($termchildren as $child) {	$term = get_term_by( 'id', $child, $taxonomyName ); ?> 
  <li><label><input value=".<?php echo $term->slug; ?>" type="checkbox"><span><?php echo $term->name; ?></span></label></li>
<? } ?>
<? } } ?>

You only need to withdraw
