我正在尝试创建一个bootstrap4嵌套手风琴（确定，已完成），但我希望通过单击外部链接来扩展（并滚动到）嵌套的可折叠。
我试图找到一个解决方案，这个答案如下：https://stackoverflow.com/a/15231860/2406704似乎离解决方案最近，但我无法让它发挥作用。我不知道它是否仍然与BS4兼容。它适用于手风琴的第一级（例如：test.html＃collapseThree）和第二级手风琴（例如：test.html＃collapseThreeBis），但由于test.html＃collapseTwo没有展开，你不会看到它。
我试图浏览test.html＃collapseTwo＃collapseThreeBis，但它也不起作用。
以下是我尝试制作的代码，但仍然不能：
