胶囊状动态选项卡只需要将以上实例的代码中 data-toggle 属性设置为 data-toggle="pill":
<!-- Nav pills -->
<ul class="nav nav-pills">
<li class="nav-item"> <a class="nav-link active" data-toggle="pill" href="#home">Home</a> </li>
<li class="nav-item"> <a class="nav-link" data-toggle="pill" href="#menu1">Menu 1</a> </li>
<li class="nav-item"> <a class="nav-link" data-toggle="pill" 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>
