本文介绍了Shinydashboard Plus修复了侧边栏之间冲突的CSS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
我正在使用包shinydashboardPlus，并希望在我的仪表板中具有两个功能-
- 完全折叠左右侧边栏
- 启动时打开两个侧边栏
在下面的示例代码中，我能够实现(1)将参数sidebar_fullCollapse = TRUE添加到dashboardPagePlus。
为了实现(2)，我使用了this post中的建议，并在正文中添加了一个标记以强制其在启动时打开，例如tags$body(class="skin-blue sidebar-mini control-sidebar-open", dashboardPagePlus(...)。
当我尝试使用(1)执行此操作时，我发现左侧菜单不再完全折叠。例如
有人能帮我解决我的冲突css来解决这个问题吗？

推荐答案
这是您问题的解决方案。造成所有差异的只是主用户界面分配标记中的"；侧边栏"；前面的一个单词。
