Question

我的网站上有一些使用折叠的元素。我想在菜单中实现指向这些元素的链接。当按下链接时，我希望元素折叠并专注于它。

我无法让这两项行动都奏效。当我从以下行中删除数据切换时：

<a class="nav-link" href="#collapsegs" data-toggle="collapse" data-target="#collapsegs" aria-expanded="false" aria-controls="collapsegs">
    Home
</a>
<div class="card">
    <div class="card-header" id="headinggs">
        <h5 class="mb-0">
             <button class="btn btn-link collapsed" data-toggle="collapse" data-target="#collapsegs" aria-expanded="false" aria-controls="collapsegs">
                 open
             </button>
        </h5>
    </div>
    <div id="collapsegs" class="collapse" aria-labelledby="headinggs" data-parent="#accordion">
        <div class="card-body">

然后滚动工作，但崩溃没有。
