下拉菜单不起作用

Question

我制作了一个带有简单 CSS 下拉菜单的 wordpress 模板。我使用的代码是我经常使用的代码，但是这次当你将鼠标悬停在按钮上而不是想将鼠标悬停在出现的下拉菜单上时，下拉菜单将消失。

有人知道我该如何解决这个问题吗？有什么问题吗？

#navigation ul {
 list-style: none;
 width: 800px;
 height: 40px;
 padding: 0;
 margin: 0 auto;
}

#navigation li {
 float: left;
 position: relative;
 z-index: 500;
 display: block;
 text-align: center;
 margin: 0px 40px;
 padding: 5px;
}

#navigation li ul {
    display: none;
    position: absolute;
   max-width: 140px;
   top: 40px;
 left: -20px;
}

ul#categories li {
 width: 100%;
  float: left;
  margin: 0;
  background: #fff;
}

ul#categories a {
 padding: 10px;
 width: 200px;
}

ul#categories li:hover{
  background: #000;
}

ul#navigation li:hover > ul,
#navigation ul li:hover > ul {
        display: block; /* display the dropdown */
}


#navigation a {
 font-family: 'Montserrat';
 color: #474747;
 text-decoration: none;
 font-weight: 300;
 letter-spacing: 2px;
 text-transform: uppercase;
 font-size: 10px;
}

li a:hover {
 color: #000;
 font-family: 'Montserrat';
}

ul#categories li a:hover {
 color: #fff;
}

<div id="bar">
<div id="navigation">
  <ul id="nav">
    <li><a href="http://todaysbeauty.nl">Home</a></li>
    <li>
      <a href="#">Categorieën</a>
      <ul id="categories">
        <li><a href="/category/travel/">travel</a></li>
        <li><a href="/category/beauty/">Beauty</a></li>
        <li><a href="/category/fashion/">Fashion</a></li>
        <li><a href="/category/lifestyle/">Lifestyle</a></li>
        <li><a href="/category/persoonlijk/">Persoonlijk</a></li>
        <div class="clear"></div>
      </ul>
    </li>
    <li>
      <a href="/over-mij" class="selected">Over mij</a>
      <div class="clear"></div>
    </li>
    <li>
      <a href="/contact">Contact</a> 
      <div class="clear"></div>
    </li>
    <li>
      <a href="/zakelijk" class="selected">Zakelijk</a>
      <div class="clear"></div>
    </li>
  </ul>
</div>

问题是您的二级菜单距离顶级菜单太低了：

#navigation li ul {
    display: none;
    position: absolute;
    max-width: 140px;
    top: 40px;/* Change this to a lower value so it overlaps or doesn't leave a gap with menu above*/
    left: -20px;
}

当光标移动到间隙时，不再处于'hover'状态，所以下拉框消失。缩小差距将解决问题。
