如何在 Opencart Admin 的产品菜单下创建子菜单

Question

我正在尝试使用 VQMOD 在产品菜单下创建子菜单，但不幸的是我无法在管理中显示它。请参阅下面我使用 VQMOD 创建菜单的代码。

<modification>
    <id>Add a link</id>
    <version>1.5.4</version>
    <vqmver>0.1</vqmver>
    <author>Nagamani Naresh</author>

    <!-- edit header controller -->
    <file name="admin/controller/common/header.php">
    <!-- create link to your page -->   
        <operation error="log">
            <search position="after"><![CDATA[$this->data['setting'] = $this->url->link('setting/store', 'token=' . $this->session->data['token'], 'SSL');]]></search>
            <add><![CDATA[
            $this->data['hello_world'] = $this->url->link('custom/helloworld', 'token=' . $this->session->data['token'], 'SSL');
            ]]></add>
        </operation>
    <!-- / -->
    </file>

    <!-- edit header template -->
    <file name="admin/view/template/common/header.tpl">
    <!-- add link to your page -->  
        <operation error="log">

            <search position="before" offset="1"><![CDATA[<ul class="right">]]></search>
            <add><![CDATA[
            <li><a class="top">Your link</a>
                <ul>
                    <li><a href="<?=$hello_world;?>">Hello World</a></li>
                </ul>
            </li>
            ]]></add>
        </operation>
    <!-- / -->
    </file> 

</modification>

对于 opencart 2。0.X 将此代码保存为 name.ocmod.xml 并从管理员上传
