Question

我无法弄清楚这一点。我有一个水平导航，菜单按钮内的子链接没有显示在按钮下面。请帮忙。谢谢。

<!--Click dropdown menu-->
    <nav class="container">
            <button class="dropbtn" onclick="dropFile()">File</button>
            <div id="myDropFile" class="dropdown-content">
                <a href="" >link 1</a>
                <a href="">link 2</a>
                <a href="">link 3</a>
            </div>
            <button class="dropbtn" onclick="dropEdit()">Edit</button>
            <div id="myDropEdit" class="dropdown-content">
                <a href="" >link 4</a>
                <a href="">link 5</a>
                <a href="">link 6</a>
            </div>
            <button class="dropbtn" onclick="dropView()">View</button>
            <div id="myDropView" class="dropdown-content">
                <a href="" >link 7</a>
                <a href="">link 8</a>
                <a href="">link 9</a>
            </div>
    </nav>

然后我的css是：

.container {
overflow: hidden;
background-color: #333;
font-family: Arial;
}

.container a {
float: left;
font-size: 16px;
color: white;
text-align: center;
padding: 14px 16px;
text-decoration: none;
}

.dropdown {
float: left;
overflow: hidden;
}

.dropbtn {
cursor: pointer;
font-size: 16px;    
border: none;
outline: none;
color: white;
padding: 14px 16px;
background-color: inherit;
}

.dropbtn:hover {
background-color: red;
}

.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}

.dropdown-content a {
float: none;
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
text-align: left;
}

.dropdown-content a:hover {
background-color: #ddd;
} 

.show {
display: block;

}

菜单链接全部显示在第一个菜单按钮下，而不是显示在每个特定按钮下。我已经尝试了所有内容并阅读了之前的所有答案。

您需要拥有一条规则，该规则会影响您悬停在div上的同级button。类似的东西：

.dropbtn:hover + .dropdown-content, .dropdown-content:hover {
  display: inline-block;
  position: absolute;
  top: 53px;
  right: inherit;
  margin-left: -60px;  
}

但是，需要修改下拉列表的位置。我会看看我是否可以把一个正在运行的例子放在一起

调整后的定位（上面的更新规则）。请参阅下面的运行示例

.container {
  overflow: hidden;
  background-color: #333;
  font-family: Arial;
}

.container a {
  float: left;
  font-size: 16px;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}

.dropdown {
  float: left;
  overflow: hidden;
}

.dropbtn {
  cursor: pointer;
  font-size: 16px;
  border: none;
  outline: none;
  color: white;
  padding: 14px 16px;
  background-color: inherit;
}

.dropbtn:hover {
  background-color: red;
}

.dropbtn:hover + .dropdown-content, .dropdown-content:hover {
  display: inline-block;
  position: absolute;
  top: 53px;
  right: inherit;
  margin-left: -60px;  
}

.dropdown-content {
  display: none;
  position: absolute;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}

.dropdown-content a {
  float: none;
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}

.dropdown-content a:hover {
  background-color: #ddd;
}

.show {
  display: block;
}

<!--Click dropdown menu-->
<nav class="container">
  <button class="dropbtn" onclick="dropFile()">File</button>
  <div id="myDropFile" class="dropdown-content">
    <a href="">link 1</a>
    <a href="">link 2</a>
    <a href="">link 3</a>
  </div>
  <button class="dropbtn" onclick="dropEdit()">Edit</button>
  <div id="myDropEdit" class="dropdown-content">
    <a href="">link 4</a>
    <a href="">link 5</a>
    <a href="">link 6</a>
  </div>
  <button class="dropbtn" onclick="dropView()">View</button>
  <div id="myDropView" class="dropdown-content">
    <a href="">link 7</a>
    <a href="">link 8</a>
    <a href="">link 9</a>
  </div>
</nav>

菜单链接未显示在菜单按钮下方
