Twitter引导多个手风琴，但一次只能打开一个面板

Question

我的页面上有3个Twitter Bootstrap手风琴，每一个都这样设置：

<div class="panel-group" id="accordion1">
    <div class="panel panel-default">
        <div class="panel-heading accordion-toggle collapsed" data-toggle="collapse" data-parent="#accordion1" data-target="#collapseOne1">
             <h4 class="panel-title">Collapsible Group Item #1</h4>
        </div>
        <div id="collapseOne1" class="panel-collapse collapse">
            <div class="panel-body">...</div>
        </div>
    </div>
    <div class="panel panel-default">
        <div class="panel-heading accordion-toggle collapsed" data-toggle="collapse" data-parent="#accordion1" data-target="#collapseTwo1">
             <h4 class="panel-title">Collapsible Group Item #2</h4>
        </div>
        <div id="collapseTwo1" class="panel-collapse collapse">
            <div class="panel-body">...</div>
        </div>
    </div>
    <div class="panel panel-default">
        <div class="panel-heading accordion-toggle collapsed" data-toggle="collapse" data-parent="#accordion1" data-target="#collapseThree1">
             <h4 class="panel-title">Collapsible Group Item #3</h4>
        </div>
        <div id="collapseThree1" class="panel-collapse collapse">
            <div class="panel-body">...</div>
        </div>
    </div>
</div>

该id“的手风琴s为像上面显示的一个，所以#accordion1，#accordion2和#accordion3。每个手风琴的面板数相同。

如何更改此设置，以便一次只能打开一个面板？目前， 每个手风琴 可以打开一个面板，这不是我想要的行为。

尝试这个：

  <div class="panel-group" id="accordion1">
    <div class="panel panel-default">
        <div class="panel-heading accordion-toggle collapsed" data-toggle="collapse" data-parent="#accordion1,#accordion2,#accordion3" data-target="#collapseOne1">
             <h4 class="panel-title">Collapsible Group Item #1</h4>

        </div>
