echo '<ul>';
echo '<li> Parent Category: ';
foreach( $categories as $category ){
     if($category->parent != 0){
          $parent_category = get_term( $category->parent );
          echo '<a href="' . esc_url( get_category_link($parent_category->term_id)) . '">' . esc_html($parent_category->name) . ' </a>';
          break;
     }
}
echo '</li>';
echo '<li>Subcategory: ';
foreach( $categories as $category ){
     if($category->parent != 0){
          echo '<a href="' . esc_url( get_category_link($category->term_id)) . '">' . esc_html($category->name) . ' </a>';
