当另一个打开时如何让引导折叠手风琴面板关闭？

Question

这是我的手风琴：

<div class="subdiv-wrapper">
    <div class="panel-group" id="accordion1_{{subdivIndex}}" ng-repeat="admin in subdivisions" ng-init="subdivIndex = $index">
        <div class="panel panel-default" id="accordion1_{{subdivIndex}}" ng-repeat="admin2 in admin.province">

            <div class="panel-heading">
                <h4 class="panel-title">
                    <a data-toggle="collapse" data-parent="accordion1_{{subdivIndex}}" href="#collapse-1{{subdivIndex}}" aria-expanded="false" ><span class="span-left">{{ admin2.name }}</span><span class="span-right">{{ admin2.population }}</span></a>
                </h4>
            </div>

            <div id="collapse-1{{subdivIndex}}" class="panel-collapse collapse">
                <div class="panel-body">
                  <h3>districts</h3>
                    <div class="panel-group" id="accordion2_{{subdivIndex}}">

                        <!-- districts -->
                        <div class="panel panel-default" ng-repeat="admin3 in admin.district" ng-init="subdivIndex2 = $index">
                            <div class="panel-heading">
                                <h4 class="panel-title">
                                    <a data-toggle="collapse" data-parent="#accordion2_{{subdivIndex}}" href="#collapse-1-1_{{subdivIndex}}_{{subdivIndex2}}"><span class="span-left">{{ admin3.name }}</span><span class="span-right" aria-expanded="false">{{ admin3.population }}</span></a> 
                                </h4>
                            </div>
                            <!-- communes -->                           
                            <div id="collapse-1-1_{{subdivIndex}}_{{subdivIndex2}}" class="panel-collapse collapse">
                                <div class="panel-body">
                                    <!-- display 'communes' title here -->
                                    <div ng-repeat="admin4 in admin3.commune"><span class="span-left">{{ admin4.name }}</span><span class="span-right">{{ admin4.population }}</span></div>
                                </div>
                            </div>
                        </div>                         
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

目前，它的功能不像通常的引导手风琴那样，每个“省”面板都会保持打开状态，直到您再次单击它。打开另一个面板时，它不会自动关闭。当父面板（省）关闭时，内部面板（区域）也不会关闭。

我看到人们使用带有面板 id 的 data-target 来完成这项工作，但我不确定如何将它与我正在使用的动态 $indexes 一起使用。
