Bootstrap 3 无法取消标记非活动选项的合理下拉按钮组

Question

在Bootstrap 3.3.7 中，我试图有一个合理的导航下拉按钮组，以便在选择后正确标记。当一个接一个地选择选项时，我遇到了在下拉按钮中标记两个菜单选项的问题。是否有下拉菜单仅标记被选中的选项，同时作为合理的组下拉导航按钮？谢谢！

<div class="row">
<div class="col-md-7">
    <div class="btn-group btn-group-justified" role="group">
        <a href="#left" class="btn btn-primary" role="button" data-toggle="tab">Left</a>
        <a href="#middle" class="btn btn-primary" role="button" data-toggle="tab">Middle</a>
        <div class="btn-group" role="group">
            <a href="#" class="btn btn-primary dropdown-toggle" data-toggle="dropdown" role="button"> Dropdown <span class="caret"></span> </a>
            <ul class="dropdown-menu">
                <li><a href="#drop1" role="tab" data-toggle="tab">drop 1</a></li>
                <li><a href="#drop2" role="tab" data-toggle="tab">drop 2</a></li>
            </ul>
        </div>
    </div>

    <div class="tab-content">
        <div class="tab-pane active" role="tabpanel" id="left">please select 1 of the options in the dropdown</div>
        <div class="tab-pane" role="tabpanel" id="middle">please try the dropdown on the right</div>
        <div class="tab-pane" role="tabpanel" id="drop1">please try select drop 2 also, then both are marked under the dropdown</div>
        <div class="tab-pane" role="tabpanel" id="drop2">please try select drop 1 also, then both are marked under the dropdown</div>
    </div>
</div>

Answer 1

我建议使用 Nav 组件而不是使用 pills 修饰符设置样式 class，而不是使用按钮组。它不一样，但非常接近，并且选项卡面板专为与药丸样式一起使用而构建。

这将解决您现在遇到的问题，因为 class 仍保留在下拉选项中。

<div>
  <ul class="nav nav-pills nav-justified" role="tablist">
    <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="pill">Home</a></li>
    <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="pill">Profile</a></li>
    <li role="presentation" class="dropdown">
      <a class="dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">
      Dropdown <span class="caret"></span>
    </a>
      <ul class="dropdown-menu">
        <li><a href="#messages" aria-controls="messages" role="tab" data-toggle="pill">Messages</a></li>
        <li><a href="#settings" aria-controls="settings" role="tab" data-toggle="pill">Settings</a></li>
      </ul>
    </li>
  </ul>

  <!-- Tab panes -->
  <div class="tab-content">
    <div role="tabpanel" class="tab-pane active" id="home">home</div>
    <div role="tabpanel" class="tab-pane" id="profile">profile</div>
    <div role="tabpanel" class="tab-pane" id="messages">messages</div>
    <div role="tabpanel" class="tab-pane" id="settings">settings</div>
  </div>
</div>
