Как отобразить только текущую категорию и подкатегории

Как отобразить только текущую категорию продукта и подкатегории. Например, я нахожусь в категории A, и я хочу видеть только категорию и подкатегории для A. Где я нахожусь в некоторой подкатегории A, я хочу видеть также категорию A и все подкатегории для A. 

  $args = array(
          'taxonomy' => 'product_cat',
          'hide_empty' => false,
          'parent'   => 0
      );
  $product_cat = get_terms( $args );

  foreach ($product_cat as $parent_product_cat)
  {

  echo '
      <ul>
        <li><a href="'.get_term_link($parent_product_cat->term_id).'">'.$parent_product_cat->name.'</a>
        <ul>
          ';
  $child_args = array(
              'taxonomy' => 'product_cat',
              'hide_empty' => false,
              'parent'   => $parent_product_cat->term_id
          );
  $child_product_cats = get_terms( $child_args );
  foreach ($child_product_cats as $child_product_cat)
  {
    echo '<li><a href="'.get_term_link($child_product_cat->term_id).'">'.$child_product_cat->name.'</a></li>';
  }

  echo '</ul>
      </li>
    </ul>';
  }

if (is_category()) {
    $cat = get_query_var('cat');
    $this_category = get_category($cat);
    $this_category = wp_list_categories('hide_empty=0&hierarchical=true&orderby=id&show_count=0&title_li=&use_desc_for_title=1&child_of='.$this_category->cat_ID."&echo=0"); // Change your parameters as your requirement

    if($this_category !='<li>No categories.</li>')
    {
     echo '<h3>Products</h3>'; 
     echo '<ul>'.$this_category.'</ul>'; 
    }
}  // if end
