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。你能在这里指出我正确的方向吗？演示：https ://codeply.com/p/t0Pb45zkuI

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