我是Bootstrap的新手。因此，如果问题不是很明智，请原谅我。
所以我有以下代码示例：

</html>现在，这是发生的点击流：
点击“扫描1结果扫描日期 - 此处有一些日期”，点击“http://localhost/api/v1/getWallet”，然后打开详细信息。现在，如果我点击“http://localhost/api/v1/getProfile”，之前打开的细节关闭，相关的细节现在打开了。现在，如果我点击“扫描2结果扫描日期 - 这里的某个日期”，然后再点击“扫描1扫描结果扫描日期 - 这里的某个日期”，最后打开的项目仍然可见。
我想要的是当我再次点击“Scan1结果扫描日期 - 这里的某个日期”然后所有内部项目都应该折叠，与现在发生的不同，最后打开的项目仍然保持打开状态。
我怎样才能做到这一点 ？
当您点击外部手风琴时，您必须折叠内部手风琴。只需在脚本文件中添加以下脚本代码即可
$("a[data-parent='#accordion'").click(function(e) {
$('.list-group-item .panel-collapse').removeClass('in');
