【问题描述】：
我的 HTML 文件中有以下代码：
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css">
<div class="list-group list-group-flush">
<a href="javascript: void(0)" data-parent=".list-group" class="list-group-item list-group-item-action filter-options" data-group="all"><b>Home</b></a>
<a data-toggle="collapse" href="#itSection" class="list-group-item list-group-item-action"><b>IT</b></a>
<div id="itSection" class="list-group collapse">
<a href="javascript: void(0)" class="list-group-item list-group-item-action menu2 filter-options" data-group="devops">DevOps</a>
</div>
<a data-toggle="collapse" href="#pdSection" class="list-group-item list-group-item-action"><b>Product
Development</b></a>
<div id="pdSection" class="list-group collapse">
<a href="javascript: void(0)" class="list-group-item list-group-item-action menu2 filter-options" data-group="travelandcppd">Travel &
CP</a>
<a href="javascript: void(0)" class="list-group-item list-group-item-action menu2 filter-options" data-group="sfandcppd">SF &
CP</a>
</div>
<a href="javascript: void(0)" class="list-group-item list-group-item-action filter-options" data-group="management"><b>Management</b></a>
<a href="javascript: void(0)" class="list-group-item list-group-item-action filter-options" data-group="marketing"><b>Marketing</b></a>
</div>
<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js"></script>
正如您在代码中看到的，我有几个带有子菜单的部分。
如果单击主页，我正在尝试使用 data-parent 属性折叠所有展开的项目。你能指出我正确的方向吗？

您可以简单地更改标记...

添加以下脚本
$("a[data-toggle='collapse']").click(() => {
$(".collapse").removeClass('show');
});

$(".collapse").removeClass('show');
