悬停时显示DIV子菜单下拉菜单
问题描述：
我正尝试使用DIV创建非常简单的悬停/下拉菜单，没有UL/LI。 我目前的代码显示菜单有3个选项，但我需要的是在链接2下有一个子菜单。 这是我目前的代码。悬停时显示DIV子菜单下拉菜单
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 0px;
font-size: 12px;
border: none;
cursor: pointer;
}
.dropdown {
margin-top:200px;
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 30px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown-content a:hover {
background-color: #f1f1f1;
}
.dropdown:hover .dropdown-content {
display: block;
bottom: 100%;
}
.dropdown:hover .dropbtn {
background-color: #3e8e41;
}
.subdiv {
display:none;
}
.dropdown:hover .subdiv {
display:block;
}<div class="dropdown">
<button class="dropbtn">^</button>
<div class="dropdown-content">
<a href="#">Link 1</a>
<a href="#">Link 2</a>
<a href="#">Link 3</a>
</div>
</div>我想什么做的是这样的：
<div class="dropdown">
<button class="dropbtn">^</button>
<div class="dropdown-content">
<a href="#">Link 1</a>
<a href="#">Link 2</a>
<div class="submenu">
<a href="#">SubLink 1</a>
</div>
<a href="#">Link 3</a>
</div>
</div>
凡SUBLINK 1项显示，当你将鼠标悬停在链接2，但一切我都试过没有按”工作，所以我希望别人可以帮助。

你可以用下面的方法做到这一点，你需要做的就是设置一个包含子菜单和悬停链接的div（这里是submenu_holder），下一步很简单，因为它与submenu_holder比下拉。
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 0px;
font-size: 12px;
border: none;
cursor: pointer;
}
.dropdown {
margin-top:200px;
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 30px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown-content a:hover {
background-color: #f1f1f1;
}
.dropdown:hover .dropdown-content {
display: block;
bottom: 100%;
}
.dropdown:hover .dropbtn {
background-color: #3e8e41;
}
.subdiv {
display:none;
}
.dropdown:hover .subdiv {
display:block;
}
.submenu {
display:none;
position:absolute;
left:60px;
top:0px;
}
.submenu_holder:hover .submenu {
display:block;
}
.submenu_holder {
position:relative;
}<div class="dropdown">
<button class="dropbtn">^</button>
<div class="dropdown-content">
<a href="#">Link 1</a>
<div class="submenu_holder">
<a href="#">Link 2</a>
<div class="submenu">
<a href="#">SubLink 1</a>
</div>
</div>
<a href="#">Link 3</a>
</div>
</div>

你在你的代码有几个问题。
对于初学者来说，子菜单的类名不对应。
下面，我裹子菜单的内容链接2.在您需要作进一步的调整，使悬停效果更加平滑...
body {
/* for demo purposes */
display: flex;
align-items: center;
justify-content: center;
height: 100vh;
}
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 0px;
font-size: 12px;
border: none;
cursor: pointer;
/* changed because the target was infuriatingly small for demo */
padding: 1em;
}
.dropdown {
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 30px;
box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
z-index: 1;
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown-content a:hover,
.submenu:hover {
background-color: #f1f1f1;
}
.dropdown:hover .dropdown-content {
display: block;
bottom: 100%;
}
.dropdown:hover .dropbtn {
background-color: #3e8e41;
}
.submenu {
padding: 12px 16px;
}
.submenu-content {
display: none;
}
.submenu-content a {
padding: 12px 0;
}
.submenu:hover .submenu-content {
display: block;
}<div class="dropdown">
<button class="dropbtn">^</button>
<div class="dropdown-content">
<a href="#">Link 1</a>
<a href="#">Link 2</a>
<a href="#">Link 3</a>
</div>
</div>
What I would like to do is this:
<div class="dropdown">
<button class="dropbtn">^</button>
<div class="dropdown-content">
<a href="#">Link 1</a>
<div class="submenu">Link 2
<div class="submenu-content">
<a href="#">SubLink 1</a>
</div>
</div>
<a href="#">Link 3</a>
</div>
</div>

这是我最终使用的代码，最适合我的情况：
<style>
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 0px;
font-size: 12px;
border: none;
cursor: pointer;
}
.dropdown {
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 30px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown-content a:hover {
background-color: #f1f1f1;
}
.dropdown:hover .dropdown-content {
display: block;
bottom: 100%;
}
.dropdown:hover .dropbtn {
background-color: #3e8e41;
}
.subdiv {
display:none;
}
.dropdown:hover .subdiv {
display:block;
}
.submenu {
display:none;
position:absolute;
left:86px;
top:0px;
background-color: #f9f9f9;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
z-index: 1;
}
.submenu_holder:hover .submenu {
display:block;
}
.submenu_holder {
position:relative;
}
</style>
<div class="dropdown">
<button class="dropbtn">^</button>
<div class="dropdown-content">
<a href="#">Link 1</a>
<div class="submenu_holder">
<a href="#">Link 2</a>
<div class="submenu">
<a href="#">SubLink 1</a>
</div>
</div>
<a href="#">Link 3</a>
</div>
</div>
