Ziz*_*olo 1 jquery twitter-bootstrap drop-down-menu vue.js
我正在制作一个小型 VueJS 页面，它将成为 SPA。下拉菜单不起作用。无论我从引导指南中复制多少内容或阅读他们的建议。事实并非如此。我缺少什么？
他们说 popper.js 它包含在 bootstrap.min.js 他们说你需要将其包装在 .dropdown 元素中 阅读 jQuery 需要在 bootstrap js 之前的 SO 问题，也做了那个
我复制了他们的例子。没有运气。
谢谢

您的下拉菜单不起作用的原因是您使用的是 5.0 Bootstrap CDN 并将其与旧的 4.0 语法配对。您需要更改语法以匹配 5.0 CDN。我已经把它写在下面了。如果有帮助的话，您可以稍后添加您的待办事项列表。
