Question

我可能在这里做错了。这是我的代码：

  ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow: auto;
    background-color: #000066;
    z-index: 1;
    }
  .header {
    position: fixed;
    top: 0;
    width: 100%;
    overflow: auto;
  }
  li {
    float: left;
    }
  li a, .dropbtn {
    display: inline-block;
    color: white;
    text-align: center;
    padding: 14px 16px;
    text-decoration: none;
    }
  li a:hover, .dropdown:hover .droptn {
    background-color: #ccb3ff;
    color: black;
    }
  .dropdown-content {
    display: none;
    position: absolute;
    background-color: #ccb3ff;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
    z-index: 2;
    }
  .dropdown-content a {
    color: black;
    padding: 12px 16px;
    text-decoration: none;
    display: block, flex;
    flex-flow: column;
    justify-content: space-evenly;
    flex-grow: 2;
    text-align: left;
    z-index: 3;
    }
  .dropdown-content a:hover {background-color: white; color: #000066;}
  .dropdown:hover .dropdown-content {display: block;}

<ul class="header">
  <li><a href="#home">Home</a></li>
  <li><a href="#about">About Us</a></li>
  <li><a href="#quote">Request a Quote</a></li>
  <li><a href="#colors">Colors</a></li>

  </div>
</li>
</ul>

显示我的下拉菜单时，它会显示在标题中，并带有一个很小的滚动条，并且不会从标题中下拉出来。我知道我可能是个白痴，这很容易解决。 A picture of what I'm talking about.我显然尝试过弄乱元素的z-indexs。它什么也没做。我已经用Google搜寻了我的小指，并且一直在尝试尝试。什么都没用。我是个假人。

您遇到的问题是，溢出被设置为自动，因此当悬停在下拉列表上并且大于分配的空间时，会导致滚动条出现。要解决此问题，请从标题和ul中删除overflow:auto。
