Здравствуйте. Имеется opencart 3.
 
	 
 
	В левом меню категорий у меня на данный момент выводятся только категории первого уровня, без вложенных подкатегорий. Нашел код, который выводит это меню:
 
	 
 
echo "<div class=\"list-group\">
  ";
        $context['_parent'] = $context;
        $context['_seq'] = twig_ensure_traversable((isset($context["categories"]) ? $context["categories"] : null));
        foreach ($context['_seq'] as $context["_key"] => $context["category"]) {
            echo "  ";
            if (($this->getAttribute($context["category"], "category_id", array()) == (isset($context["category_id"]) ? $context["category_id"] : null))) {
                echo " 
  <a href=\"";
                echo $this->getAttribute($context["category"], "href", array());
                echo "\" class=\"list-group-item active\">";
                echo $this->getAttribute($context["category"], "name", array());
                echo "</a> 
  ";
                if ($this->getAttribute($context["category"], "children", array())) {
                    echo "  ";
                    $context['_parent'] = $context;
                    $context['_seq'] = twig_ensure_traversable($this->getAttribute($context["category"], "children", array()));
                    foreach ($context['_seq'] as $context["_key"] => $context["child"]) {
                        echo "  ";
                        if (($this->getAttribute($context["child"], "category_id", array()) == (isset($context["child_id"]) ? $context["child_id"] : null))) {
                            echo "  <a href=\"";
                            echo $this->getAttribute($context["child"], "href", array());
                            echo "\" class=\"list-group-item active\">   - ";
                            echo $this->getAttribute($context["child"], "name", array());
                            echo "</a>                        
  ";
 
                        } else {
                            echo " 
  <a href=\"";
                            echo $this->getAttribute($context["child"], "href", array());
                            echo "\" class=\"list-group-item\">   - ";
                            echo $this->getAttribute($context["child"], "name", array());
                            echo "</a>
  ";
                        }
                        echo "  ";
                    }
                    $_parent = $context['_parent'];
                    unset($context['_seq'], $context['_iterated'], $context['_key'], $context['child'], $context['_parent'], $context['loop']);
                    $context = array_intersect_key($context, $_parent) + $_parent;
                    echo "  ";
                }
                echo "  ";
            } else {
                echo " <a href=\"";
                echo $this->getAttribute($context["category"], "href", array());
                echo "\" class=\"list-group-item\">";
                echo $this->getAttribute($context["category"], "name", array());
                echo "</a>
  ";
            }
            echo "  ";
        }
        $_parent = $context['_parent'];
        unset($context['_seq'], $context['_iterated'], $context['_key'], $context['category'], $context['_parent'], $context['loop']);
        $context = array_intersect_key($context, $_parent) + $_parent;
        echo "</div>
";
