在子類別頁面中顯示主要類別

Question

我有一個Woocommerce網站。 在my.domain.com/shop中，我有一個顯示所有類別的菜單。 單擊主要類別時，頁面會加載帶有子類別的內容，但主要類別會消失。

示例：我有一個像這樣的菜單

Menu 1 Menu 2 Menu 3

當我單擊菜單1時，我得到的是這樣的：

Submenu 1

我想要實現的是，當我單擊菜單1時，我想要得到這個：

Menu 1 Menu 2 Menu 3

Submenu 1

woocommerce.php看起來像這樣：

$parentid = get_queried_object_id();
                $args = array(
                    'number'     => $number,
                    'orderby'    => $orderby,
                    'order'      => $order,
                    'hide_empty' => $hide_empty,
                    'include'    => $ids,
                    'parent' => $parentid

                );
                $product_categories = get_terms( 'product_cat', $args );
                $current_cat = $wp_query->query['product_cat'];
                echo '<ul class="product_cats">';
                foreach ($product_categories as $category) {
                    if($category->slug == $current_cat) {
                        $active_class = 'class="active"';
                    } else {
                        $active_class = null;
                    }
                    echo '<li><a '. $active_class .' href="'. 
                    get_term_link($category) .'">'. $category->name .'</a></li>';

                }
                echo '</ul>';
