为什么子子菜单不符合其父级的权利?

我在网站的导航栏上工作,但我特别在子菜单上遇到问题。我注意到子菜单没有正确地与右边界上的父母对齐。事实上,所有这些都与主导航栏的顶部对齐。

例如,"基本权利"的子子菜单。和#34;了解我们的空间"都显示在顶部,而不是在其父级旁边正确对齐。如果有人能解释为什么会发生这种情况会很棒。非常感谢你!

这是live example

这是HTML:

        <!-- Navigation Bar -->
    <div class="nav">


        <!-- Quick Close -->
        <button id="get-away">QUICK CLOSE</button>


        <!-- Search Bar 
        <form action="./search.php" method="get">
            <input type="text" name="input" size="40px"/>
            <input type="submit" value="SEARCH"/>
        </form> -->


            <!-- Sticky Navigation -->
    <div class="nav-wrapper">

将此添加到您的CSS中,我猜它会正常工作!

  .nav-wrapper > ul > li > ul > li {
    position:relative;
  }

要解决此问题,请将position: relative;添加到.nav ul ul li

.nav ul ul li {
  display: block;
  text-align: left;
  position: relative; /* <-- Add this */
}
