我被分配重新制作一个 Drupal 网站，我必须在其中实现一个下拉菜单。它在 IE8、Chrome、Firefox 上运行良好，但在 IE6 上不行（而且本网站的大多数用户都使用 IE6...） 模块是 Superfish，下面是一些代码：
<body class="homepage">
<div id="global">
<div id="header">
<div id="header-content">
<div class="fil-ariane">You are here : Home</div>
<div class="search">search stuff</div>
<div id="block-superfish-1"
class="block block-superfish contextual-links-region">
<div
class="contextual-links-wrapper contextual-links-processed">
<div class="content">
<ul id="superfish-1"
class="menu sf-menu sf-menu-menu-header sf-horizontal sf-style-sna_superfish sf-total-items-3 sf-parent-items-1 sf-single-items-2 nav superfish-processed">
<li id="menu-477-1"
class="first odd sf-item-1 sf-depth-1 sf-no-children">
<li id="menu-501-1"
class="middle even sf-item-2 sf-depth-1 sf-no-children">
<li id="menu-983-1"
class="last odd sf-item-3 sf-depth-1 sf-total-children-3 sf-parent-children-0 sf-single-children-3 menuparent">
<a class="sf-depth-1 menuparent"
href="LIEN_homepage/#">USEFUL LINKS</a>
<ul>
<li id="menu-986-1"
class="first odd sf-item-1 sf-depth-2 sf-no-children">
<a class="sf-depth-2" href="LINK1">text_link1</a>
</li>
<li id="menu-985-1"
class="middle even sf-item-2 sf-depth-2 sf-no-children">
<a class="sf-depth-2" href="LINK2">text_link2</a>
</li>
<li id="menu-984-1"
class="last odd sf-item-3 sf-depth-2 sf-no-children">
<a class="sf-depth-2" href="LINK3">text_link3</a>
</li>
</ul>
</li>
</ul>
</div>
</div>
</div>
</div>
</div>
</div>
这是CSS：

我猜并不是所有的东西都有用，但我找到了一些解决方案，其中附近的 div/类的样式（属性'位置'，'显示'）很重要。
我的问题是：如何使该菜单出现在 IE6 上？仅仅是造型的问题吗？我必须制作一些 javascript 吗？
