大菜单有助于添加另一个 link 按钮

Question

我正在查看 w3schools 网站上的大型菜单：(https://www.w3schools.com/howto/howto_css_mega_menu.asp)。

使用 "try it yourself"，我一直在玩弄它，但很难看到如何在 dropdown [=20= 旁边添加另一个大型菜单或另一个 link 按钮].

谁能帮帮我？

Answer 1

为您提供超级菜单的代码如下：

<div class="dropdown">
<button class="dropbtn">Dropdown 
  <i class="fa fa-caret-down"></i>
</button>
<div class="dropdown-content">
  <div class="header">
    <h2>Mega Menu</h2>
  </div>   
  <div class="row">
    <div class="column">
      <h3>Category 1</h3>
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
    <div class="column">
      <h3>Category 2</h3>
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
    <div class="column">
      <h3>Category 3</h3>
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
    </div>
  </div>
</div>

希望这就是您要找的。
