九、动态选项卡

如果你要设置选项卡是动态可切换的，可以在每个链接上添加 data-toggle="tab" 属性。 然后在每个选项对应的内容的上添加 .tab-pane 类。

如果你希望有淡入效果可以在 .tab-pane 后添加 .fade类:

<!-- Nav tabs -->
<ul class="nav nav-tabs">
  <li class="nav-item">
    <a class="nav-link active" data-toggle="tab" href="#home">Home</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#menu1">Menu 1</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#menu2">Menu 2</a>
  </li>
</ul>
 
<!-- Tab panes -->
<div class="tab-content">
  <div class="tab-pane active container" id="home">...</div>
  <div class="tab-pane container" id="menu1">...</div>
  <div class="tab-pane container" id="menu2">...</div>
</div>
