如何在自定义菜单模板中显示“选定页面”？

我正在使用DDR菜单令牌模板在DNN中创建自己的自定义菜单。

在我的菜单中，我希望选择我当前所在页面的菜单链接。我可以通过使用令牌来实现[SELECTED]。但是，无论何时我进入第二层或第三层页面，都不会选择该链接。如何编写代码，以便即使我在“子级”页面中也可以选择“父级页面链接”？

这是我的代码

[>NODE-TOP]
<li class="[?NODE]dropdown[/?][?SELECTED] current active[/?]">
    [?ENABLED]
        <a class="dropdown-toggle forcelink" data-toggle="dropdown" data-hover="dropdown" data-delay="300" href="[=URL]">[=TEXT]<span class="[?NODE]caret[/?]"></a>
    [/?]
    [?NODE]
        <ul class="dropdown-menu">
            [*>NODE]
        </ul>
    [/?]
</li>
[/>]
[>NODE]
<li class="dropdown-submenu">
    [?ENABLED]
            <a href="[=URL]">[=TEXT]<span class="[?NODE]caret-right[/?]"></a>
    [/?]
    [?NODE]
        <ul class="dropdown-menu">
            [*>NODE]
        </ul>
    [/?]
</li>
[/>]

以下是一些可用于DDRMenu的令牌：
