在 shinyDashboard 中的 menuSubItems 之间切换

Question

我正在尝试使用 shinydashboard 设置一个闪亮的应用程序，在大多数情况下，祝你好运。但是，我运行对侧边栏行为感到怪异，我认为这是可以避免的，但还没有找到如何避免的。

下面是一个重现我遇到的问题的小例子。基本上，有两个 sidebarMenus - 菜单一和菜单二，每个都有两个 menuSubItems。在菜单项中切换子项工作正常。所以，如果我想从 subItemOne 切换到 subItemTwo，没问题。我可以整天这样做。

我还可以跨菜单切换到子项，例如从 subItemOne 跳到 subItemThree，这很好。问题在于试图切换回来。如果选择了 subItemOne，我尝试转到 subItemThree 并返回到 subItemOne，我做不到。我必须转到 subItemTwo，然后才能打开 SubItemOne。

有没有办法更正此设置，以便我可以直接从 subItemOne 跳到 subItemThree（或二和四）然后再返回？

问题是选项卡项目保持活动状态，单击活动选项卡项目不会更新 UI。这可以用一些 Javascript.

来解决

library('shiny')
library('shinydashboard')
# Sidebar #############################
sidebar <- dashboardSidebar(
  tags$head(
    tags$script(
      HTML(
        "
        $(document).ready(function(){
          // Bind classes to menu items, easiet to fill in manually
          var ids = ['subItemOne','subItemTwo','subItemThree','subItemFour'];
          for(i=0; i<ids.length; i++){
            $('a[data-value='+ids[i]+']').addClass('my_subitem_class');
          }

          // Register click handeler
          $('.my_subitem_class').on('click',function(){
            // Unactive menuSubItems
            $('.my_subitem_class').parent().removeClass('active');
          })
        })
        "
      )
    )
  ),
  width = 290,

  sidebarMenu(
    menuItem('Menu One', tabName = 'menuOne', icon = icon('line-chart'),
             collapsible = 
               menuSubItem('Sub-Item One', tabName = 'subItemOne'),
             menuSubItem('Sub-Item Two', tabName = 'subItemTwo')
    )
  ),

  sidebarMenu(
    menuItem('Menu Two', tabName = 'menuTwo', icon = icon('users'), 
             collapsible = 
               menuSubItem('Sub-Item Three', tabName = 'subItemThree'),
             menuSubItem('Sub-Item Four', tabName = 'subItemFour')
    )
  )

)
# Body #############################
body <- dashboardBody(

  tabItems(
    tabItem(tabName = 'subItemOne',
            h2('Selected Sub-Item One')
    ),
    tabItem(tabName = 'subItemTwo',
            h2('Selected Sub-Item Two')
