菜单打开时,导航栏位于页面上的内容下方

标签: html css

我的页面上有这个表格,下面给出了导航栏的css 问题是当菜单从导航栏落下时,它就在桌子下方。显然我希望它能够保持在页面上的每一个上面。

<div class="row" style="margin-top: 50px;">
        <div class="col-lg-12">
            <table class="table table-bordered">
            <tbody>
            <tr>
            <th class="info">o</th>
            <th class="info">Td</th>
            <th class="info">jdj</th>
            <th class="info">jd</th>
            <th class="info">js</th>
            </tr>
            <script type="text/javascript">

       cssmenu.find('li ul').parent().addClass('has-sub');
    multiTg = function() {

我似乎无法找到我在哪里出错。任何帮助将非常感激。我希望当菜单落下时,内容仍然在所有内容的顶部,但它会在我的页面上的桌子下面。我花了几个小时寻找我做错了什么,但我可以忽略我的最小错误。请帮助!

我并非100%关注您的代码如何工作,但确保导航栏的z-index大于表的z-index(如果有的话)应该有效。
