Question

是否有一种方法或扩展可以修改类别模块，因此它只显示当前顶级类别页面的子类别。

例如，如果我在“笔记本电脑和台式机”类别页面上，侧边栏模块将仅列出与“笔记本电脑和台式机”类别相关联的子类别，例如“Macs”和“PC”标题为“笔记本电脑和桌面”（并未列出或显示任何其他顶级类别）。

按以下方式更新foreach中的catalog/controller/module/category.php部分，仅显示左列中的子类别。

    $cur_category_id = $this->data['category_id']; // new code 
    foreach ($categories as $category) {
        $children_data = array();

        $children = $this->model_catalog_category->getCategories($category['category_id']);

        foreach ($children as $child) {
            $data = array(
                'filter_category_id'  => $child['category_id'],
                'filter_sub_category' => true
            );

            $children_data[] = array(
                'category_id' => $child['category_id'],
                'name'        => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($data) . ')' : ''),
                'href'        => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id']) 
            );  

            if($cur_category_id && $cur_category_id == $category['category_id']){
                $this->data['heading_title'] =  $category['name'];
                $this->data['categories'][] = array(
                    'category_id' => $child['category_id'],
                    'children'    => array(),
                    'name'        => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($data) . ')' : ''),
                    'href'        => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id']) 
                );
            }
        }

        $data = array(
            'filter_category_id'  => $category['category_id'],
            'filter_sub_category' => true
        );
        /*
        $this->data['categories'][] = array(
            'category_id' => $category['category_id'],
            'name'        => $category['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($data) . ')' : ''),
            'children'    => $children_data,
            'href'        => $this->url->link('product/category', 'path=' . $category['category_id'])
        );  */
    }

注意：由于我之前在您的问题中添加了评论，因此只会显示子类别，并且不会有任何选项来选择添加到父类别的产品。

度过愉快的一天:) !!
