Question

我想为网站创建一个下拉菜单，但我的菜单项只显示在右侧，但我希望它们显示在选项上方。我该如何解决这个问题？

也会感谢一些帮助，找出如何更正代码，让我将鼠标悬停在可用的下拉菜单选项上。

以下是网站的链接，如果有人想查看它，看看代码是什么样的。

将position: fixed更改为position: absolute并为left设置bottom和.dropdown-content个职位，并将li设置为position: relative; < / p>

ul li {
  position: relative;
}

.dropdown-content {
    display: none;
    position: absolute;
    bottom: 30px; /* or something */
    left: 0;
    background-color: #f9f9f9;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}

并从overflow: hidden移除ul ......
