Superfish 二级 ul 非常小

Question

问题是我网站上的超级鱼菜单： http://alexander-pastor.de/

当鼠标悬停在顶层ul的li上时，子ul只有16px的高度。我无法以某种方式修复它。向 ul 或 li 添加 height/min-height css-property 似乎不起作用。

我通过 jQuery 将 sf-menu 类添加到 ul，因为它是来自 contao-module 的自动生成代码。它由导航元素包裹。像这样：

<nav class="mod_navigation block">
    <ul class="level_1 sf-menu">
        <li>
           <ul>...
        </li>
        ... ...
        ... ...
     </ul>
 </nav>

如果有人可以调查一下，我将不胜感激：D

我正在使用最新版本的超级鱼。 我在 head-tag 中包含以下内容：

<script type="text/javascript">


    $(document).ready( function() {
        $('#header-navigation ul.level_1').addClass('sf-menu');
    });

    $(document).ready(function(){

        // initialise plugin
        var example = $('#header-navigation ul.level_1').superfish({});

    });

</script>

<script type="text/javascript" src="files/version9/plugins/superfish/superfish.js">       </script>
<script type="text/javascript" src="files/version9/plugins/superfish/hoverIntent.js"></script>

superfish.css 包含：

.sf-menu, .sf-menu * {
    margin: 0;
    padding: 0;
    list-style: none;

.sf-menu li {
    position: relative;

应该不会和我的default.css冲突吧？！

default.css - 包含 #header** 的部分

#header {
    border-radius:...;

    color:#fff;
}

#header a{
    color:#fff;
    text-decoration:none;
}

#header-menu{
    width:1000px;
    height:46px;

    background: ...;

    text-align: center;

    border-radius...
}

#header-menu-elements{
    margin:5px 0;
}

#header-menu-elements{
    height:36px;
    float:left;
    background:transparent;
}

#header-navigation{
    height:40px;
    background:...;
    border-radius:...;
}

这不是因为 height 属性。您的.block 有一个overflow: hidden;（也位于您的nav），这会导致您的子导航的主要部分不可见。
