悬停时显示DIV子菜单下拉菜单 [英] Show DIV submenu dropdown when hovering

问题描述

我试图使用DIV创建一个非常简单的悬停菜单，而不使用UL/LI. 我当前的代码显示了带有3个选项的菜单，但是我需要在Link 2下有一个子菜单. 这是我当前的代码.

I am trying to create a very simple hover/drop menu using DIVs, no UL/LI. My current code shows the menu with 3 options, but what I need is to have a submenu under Link 2. Here is my current code.

    .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>

我想做的是这样

<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>

当您将鼠标悬停在链接2上时，出现SubLink 1项的位置，但是我尝试过的所有方法均无效，因此希望其他人可以提供帮助.

Where the SubLink 1 item shows up when you hover over Link 2, but everything I have tried doesn't work, so I'm hoping someone else can help.

推荐答案

您可以执行以下操作，只需设置一个div(此处为submenu_holder)，该div包含子菜单和指向悬停的链接，下一步很简单，因为submenu_holder与下拉菜单是相同的过程.

you can do that with the following, all you need to do is to set a div (here submenu_holder) that contains the submenu and the link to hover, the next step is straightforward, as it is the same process with submenu_holder than with dropdown.

    .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>
