html - Superfish 二级 ul 非常小

Question

问题是我网站上的 superfish 菜单: http://alexander-pastor.de/

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

我通过 jQuery 将类 sf-menu 添加到 ul，因为它是从 contao 模块自动生成的代码。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>

如果有人能研究一下，我将不胜感激:D

我使用的是最新版本的 superfish。我在 head-tag 中包含了以下内容:

<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 {

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:...;
}

这不是因为高度属性。你的 .block 有一个 overflow: hidden; (也在你的 nav 上)，这导致你的子导航的主要部分不是可见。
