Jquery 仅使一个子类别在引导和角度中折叠

我正在使用jquery和bootstrap，我有一个下拉列表，单击该类别就会打开。但我一次只想扩展一个类别。如果任何其他类别已展开，则单击其他类别时，展开的类别应折叠

<div class="row">
    <div class="col-md-offset-1 col-md-3 col-sm-offset-0 col-sm-4">
        <div id="menu">
            <div class="panel list-group">
                <a href="" class="list-group-item" id="heading">
                    <strong>Browse By Categories</strong>
                </a>
                <div>
                    <a class="list-group-item" data-toggle="collapse" data-target="#AAA" data-parent="#menu">
                        AAA <span class="glyphicon glyphicon-chevron-down pull-right"></span>
                    </a>
                    <div id="AAA" class="sublinks collapse">
                        <a class="list-group-item small">
                            <span class="glyphicon glyphicon-chevron-right"></span> aaaa
                        </a>
                        <a class="list-group-item small">
                            <span class="glyphicon glyphicon-chevron-right"></span> aaaa
                        </a>
                        <a class="list-group-item small">
                            <span class="glyphicon glyphicon-chevron-right"></span> aaaa
                        </a>
                        <a class="list-group-item small">
                            <span class="glyphicon glyphicon-chevron-right"></span> aaaa
                        </a>
                    </div>
                <a class="list-group-item" data-toggle="collapse" data-target="#BBB" data-parent="#menu">
                        BBB <span class="glyphicon glyphicon-chevron-down pull-right"></span>
                    </a>
                    <div id="BBB" class="sublinks collapse">
                        <a class="list-group-item small">
                            <span class="glyphicon glyphicon-chevron-right"></span> aaaa
                        </a>
                        <a class="list-group-item small">
                            <span class="glyphicon glyphicon-chevron-right"></span> aaaa
                        </a>
                        <a class="list-group-item small">
                            <span class="glyphicon glyphicon-chevron-right"></span> aaaa
                        </a>
                        <a class="list-group-item small">
                            <span class="glyphicon glyphicon-chevron-right"></span> aaaa
                        </a>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

谢谢。
我认为您需要手风琴组件，下面是一个使用引导的示例：

function toggleChevron(e) {
$(e.target)
    .prev('.panel-heading')
    .find("i.indicator")
    .toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
}
$('#accordion').on('hidden.bs.collapse', toggleChevron);
$('#accordion').on('shown.bs.collapse', toggleChevron);
