Accordion multiple 展开问题

<div data-toggle="topjui-accordion" data-options="multiple:true">

<div title="定位报表">
<ul class="rep_ul">
<li data-id="history">历史轨迹</li>
<li data-id="rate">轨迹完整率</li>
</ul>
</div>

<div title="里程报表">
<ul class="rep_ul">
<li data-id="mileage">里程统计[天]</li>
</ul>
</div>

<div title="报警报表">
<ul class="rep_ul">
<li data-id="police">报警统计分析</li>
</ul>
</div>

<div title="在线率报表">
<ul class="rep_ul">
<li data-id="car">车辆在线率</li>
</ul>
</div>
</div>



为什么 multiple 设置为true 还是无法全部展开呢？
