jquery-ui – Twitter Bootstrap：如何创建一个带有手风琴的下拉按钮？

在Twitter Bootstrap中,我正在尝试创建一个带有手风琴的按钮下拉列表.

目的是以简明的形式呈现一长串项目(即避免用户长时间向下滚动).

在dropdown div中包含手风琴div的简单方法不起作用..：

<div class="dropdown">
    <a data-toggle="dropdown" href="#">Dropdown trigger</a>
    <div class="dropdown-menu" role="menu" aria-labelledby="dLabel" id="accordion">
    <h3>Unit 1</h3>
    <div>
      <p>item a</p>
      <p>item b</p>
    </div>
    <h3>Unit 2</h3>
    <div>
      <p>item c</p>
      <p>item d</p>
      <p>item e</p>
    </div>
  </div>            
</div>

任何想法如何实现这一点？

解决方法

您可以使用以下方法在下拉列表中插入手风琴：

> Bootstrap Dropdown component
> Bootstrap Collapse component

您需要添加几行JS以防止Dropdown事件破坏崩溃事件.

Working example on Bootply

<div class="dropdown dropdown-accordion" data-accordion="#accordion">
  <a data-toggle="dropdown" href="#" class="btn btn-primary">Dropdown trigger <span class="caret"></span></a>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
    <li>
      <div class="panel-group" id="accordion">
        <div class="panel panel-default">
          <div class="panel-heading">
            <h4 class="panel-title">
              <a data-toggle="collapse" data-parent="#accordion" href="#collapSEOne">
                Unit 1
              </a>
            </h4>
          </div>
          <div id="collapSEOne" class="panel-collapse collapse">
            <div class="panel-body">
              <a href="#">Item a</a><br>
              <a href="#">Item b</a>
            </div>
          </div>
        </div>
        <div class="panel panel-default">
          <div class="panel-heading">
            <h4 class="panel-title">
              <a data-toggle="collapse" data-parent="#accordion" href="#collapseTwo">
                Unit 2
              </a>
            </h4>
          </div>
          <div id="collapseTwo" class="panel-collapse collapse">
            <div class="panel-body">
              <a href="#">Item a</a><br>
              <a href="#">Item b</a><br>
              <a href="#">Item c</a>
            </div>
          </div>
        </div>
      </div>
    </li>
  </ul>
</div>

.dropdown-accordion .panel-heading {
  padding: 0;
}
.dropdown-accordion .panel-heading a {
  display: block;
  padding: 10px 15px;
}

// Collapse accordion every time dropdown is shown
$('.dropdown-accordion').on('show.bs.dropdown',function (event) {
  var accordion = $(this).find($(this).data('accordion'));
  accordion.find('.panel-collapse.in').collapse('hide');
});

// Prevent dropdown to be closed when we click on an accordion link
$('.dropdown-accordion').on('click','a[data-toggle="collapse"]',function (event) {
  event.preventDefault();
  event.stopPropagation();
  $($(this).data('parent')).find('.panel-collapse.in').collapse('hide');
  $($(this).attr('href')).collapse('show');
})
