Bootstrap 手风琴不会在一页上展开答案

【问题标题】：Bootstrap accordion won't expand on one pageBootstrap 手风琴不会在一页上展开
【发布时间】：2021-12-22 12:11:33
【问题描述】：

在我的索引页面上，我使用了来自 getbootstrap.com 的示例代码，现在我想在同一站点的不同页面上再次使用它。它显示得很好，但没有响应并且不会展开/折叠。

两个页面的标题内容完全相同 - 字面意思是复制/粘贴。我不是编码方面的专业人士 - 有什么想法吗？谢谢！

It's also worth noting that just about any HTML can go within the <code>.accordion-body</code>, though the transition does limit overflow.

标签： bootstrap-5 bootstrap-accordion

【解决方案1】：

找到答案。我忘了把 JS/popper 脚本放在页面末尾。

【讨论】：

附注 Chris，如果您使用 Bootstrap 5 Bundle JS，则包含 Popper。您在页面中调用 Bootstrap 的方式假定没有 Popper，然后您添加了 popper。您可以通过为 Bootstrap Bundle 添加一行来获得全部内容。这一切都在文档中。顺便说一句，在挖掘答案方面做得很好。
