我在opencart管理面板中添加了4个类别作为4级，
Home
Home -> Furniture
Home -> Furniture -> Wooden (Getting menus up to this level)
Home -> Furniture -> wooden -> Lightweight (Need to display this level)
最初我在菜单中显示第3级别类别时出现问题。 我使用此post
启用了第三级菜单像这样如何启用第4级别类别。

首先从here下载vqmod然后解压缩。现在vqmod文件夹保存在您的站点根目录中。然后转到浏览器编写您的站点URL然后“/ vqmod / install”并按Enter键，然后您会收到一条消息，您可以在您的站点中成功安装vqmod。现在，您下载扩展表单here并将其解压缩。并在你的站点中保存提取文件，在你的站点中指示foulder exm：menu3rdlevel-opencart-2_2 \ vqmod \ xml / Menu3rdLevel.xml文件，例如：vqmod \ xml / Menu3rdLevel.xml，其他文件带有“menu3rdlevel”文件夹。从您的扩展文件夹“javascript”到您的站点文件夹“javescript”，扩展文件夹“image”到站点文件夹“image”扩展文件夹“stylsheet”到站点文件夹“stylsheet”。然后在浏览器中刷新您的网站即可。
注意：使用“menu3rdlevel”文件夹传输仅xml文件和其他文件。

用于在主菜单中显示子类别。请进行以下更改。
编辑header.php控制器文件
$sec_children_data = array();
$sec_children = $this->model_catalog_category->getCategories($child['category_id']);
foreach ($sec_children as $sec_child) {
$sec_children_data[] = array(
'name' => $sec_child['name'] . ($this->config->get('config_product_count') ? '' : ''),
'href' => $this->url->link('product/category', 'path=' . $child['category_id'] . '_' . $sec_child['category_id'])
);
}
编辑header.tpl
?php if (isset($category['children'][$i]['level3'])) {
$level3menus = $category['children'][$i]['level3'];
?>
<ul class="level3">
<?php
foreach( $level3menus as $level3menu) {
?>
<li><a href="<?php echo $level3menu['href']; ?>" class=""><?php echo $level3menu['name'];?></a></li>
<?php } ?>
请参阅我的教程，了解分步说明和演示。
