本文介绍了Bootstrap 4 嵌套折叠“数据父级"不工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想使用折叠数据父选项.我需要传统的手风琴行为:当显示可折叠项目时，应关闭指定父项下的所有可折叠元素.但它不起作用.不知道是不是我的嵌套折叠造成的，还是我做错了什么.

可能我不得不添加一些js.但是代码不应该是多余的.
解决方案
它不起作用，因为 data-parent 属性应该是可折叠 (.collapse) 元素，而不是 data-toggle(触发器)元素...

I want to use collapse data-parent options. I need traditional accordion behavior: all collapsible elements under the specified parent should be closed when a collapsible item is shown. But it doesn't work. I don't know if that's because of my nested collapse or I do something wrong.

Probably I had to add some js. But the code should not be redundant.
解决方案
It's not working because the data-parent attribute should be the collapsible (.collapse) element, instead of the data-toggle (trigger) element...
