我的菜单图标不工作时，用户在移动终端上，它也不工作时，我检查页面，并尝试运行响应设备上的页面.我怎样才能解决这个问题，以便当用户访问页面时，他/她可以点击菜单图标，并看到我的导航项目？

所有JavaScript插件的数据属性现在都有命名空间，以帮助区分Bootstrap功能与第三方和您自己的代码。例如，我们使用data-bs-toggle代替data-toggle。

Bootstrap 5更改了数据属性的命名，这些属性通常由使用JavaScript作为其功能一部分的组件使用。
以前，大多数依赖于某些JavaScript功能的组件都有以data-开头的数据属性。在Bootstrap 5中，这些组件的数据属性现在以data-bs开头，以便轻松命名Bootstrap属性。

数据-BS-触发而不是数据-触发。
数据BS目标而不是数据目标。
