Question

Bootstrap是否根据我上传的图片提供功能或类似功能谢谢！

Answer 1

是的，在Twitter bootstrap中你可以做这样的事情并将它附加到一个静态按钮，然后将它放在导航栏上，就像你的例子中那样：

<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu">
  <li><a tabindex="-1" href="#">Action</a></li>
  <li><a tabindex="-1" href="#">Another action</a></li>
  <li><a tabindex="-1" href="#">Something else here</a></li>
  <li class="divider"></li>
  <li><a tabindex="-1" href="#">Separated link</a></li>
</ul>

有关更多组件，请参阅here

在jfiddle和另一个here上还有一个类似元素的实例，当我使用twitter bootstrap对它们进行测试时，它们都有效。

 $( document.body ).on( 'click', '.dropdown-menu li', function( event ) {

      var $target = $( event.currentTarget );

      $target.closest( '.btn-group' )
         .find( '[data-bind="label"]' ).text( $target.text() )
            .end()
         .children( '.dropdown-toggle' ).dropdown( 'toggle' );

      return false;

   });

.btn-input {
   display: block;
}

.btn-input .btn.form-control {
    text-align: left;
}

.btn-input .btn.form-control span:first-child {
   left: 10px;
   overflow: hidden;
   position: absolute;
   right: 25px;
}

.btn-input .btn.form-control .caret {
   margin-top: -1px;
   position: absolute;
   right: 10px;
   top: 50%;
}

此示例使用bootstrap 2.3.2而不是3。

Answer 2

Bootstrap已经具有该功能内置功能。您甚至不必自己编写一行JavaScript。
