Show content for menuItem when menuSubItems exist in Shiny Dashboard

Is there a way of actually showing content in the content pane of a Shiny Dashboard for a menuItem with existing menuSubItems. In the example: I tried to add "tabName = "charts"" to the menuItem "Charts" in order to show the content of tabItem "charts". However, no effect besides opening the menu and showing the submenu (the content pane still shows the "old" content of the previous selection):

    subtitle = a(href = "#", icon("circle", class = "text-success"), "Online"),
    # Image file should be in www/ subdir
    image = "userimage.png"
  ),
  sidebarSearchForm(label = "Enter a number", "searchText", "searchButton"),
  sidebarMenu(
    # Setting id makes input$tabs give the tabName of currently-selected tab
    id = "tabs",
    menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
    menuItem("Widgets", icon = icon("th"), tabName = "widgets", badgeLabel = "new",
             badgeColor = "green"),
    menuItem("Charts", icon = icon("bar-chart-o"),
      menuSubItem("Sub-item 1", tabName = "subitem1"),
      menuSubItem("Sub-item 2", tabName = "subitem2")

Much credit goes to this question React to menuItem() tab selection . The only annoying thing is that you would have to click on the Charts tab again but I think that should be fine

library(shiny)
library(shinydashboard)

convertMenuItem <- function(mi,tabName) {
  mi$children[[1]]$attribs['data-toggle']="tab"
  mi$children[[1]]$attribs['data-value'] = tabName
  if(length(mi$attribs$class)>0 && mi$attribs$class=="treeview"){
    mi$attribs$class=NULL
  }
  mi
}

header <- dashboardHeader()

sidebar <- dashboardSidebar(
  sidebarUserPanel("Pork Chop",
                   subtitle = a(href = "#", icon("circle", class = "text-success"), "Online"),
                   # Image file should be in www/ subdir
                   image = "https://vignette.wikia.nocookie.net/fanfictiondisney/images/9/9e/Pumba_3.jpg/revision/latest?cb=20120708163413"
  ),
  sidebarSearchForm(label = "Enter a number", "searchText", "searchButton"),
  sidebarMenu(
    # Setting id makes input$tabs give the tabName of currently-selected tab
    id = "tabs",
    menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
    menuItem("Widgets", icon = icon("th"), tabName = "widgets", badgeLabel = "new", badgeColor = "green"),
    convertMenuItem(menuItem("Charts", tabName = "charts",icon = icon("bar-chart-o"),selected=T,
             menuSubItem("Sub-item 1", tabName = "subitem1"),
             menuSubItem("Sub-item 2", tabName = "subitem2")),"charts")
  )
)

body <- dashboardBody(
  tabItems(
    tabItem("dashboard",div(p("Dashboard tab content"))),
    tabItem("widgets","Widgets tab content"),
    tabItem("charts","Charts Tab"),
    tabItem("subitem1","Sub-item 1 tab content"),
    tabItem("subitem2","Sub-item 2 tab content")
  )
)

shinyApp(
  ui = dashboardPage(header, sidebar, body),
  server = function(input, output) { }
)

Coming from here. This is an alternative approach showing a hidden, childless menuItem associated with a tabItem, once the childful menuItem is expanded.

Two advantages over @PorkChop's current solution are, that input$sidebarItemExpanded remains functional (doesn't get updated when using convertMenuItem) and there is no second click needed to expand the menu.

library(shiny)
library(shinydashboard)
library(shinyjs)

ui <- dashboardPage(
  dashboardHeader(), 
  dashboardSidebar(
    sidebarMenu(
      id = "sidebarID",
      menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
      menuItem("Widgets", icon = icon("th"), tabName = "widgets"),
      menuItem("Charts", id = "chartsID", tabName = "charts", icon = icon("bar-chart-o"), expandedName = "CHARTS",
                               menuSubItem("Sub-item 1", tabName = "subitem1"),
                               menuSubItem("Sub-item 2", tabName = "subitem2")
      ),
      hidden(menuItem("hiddenCharts", tabName = "hiddenCharts"))
    )
  ),
  dashboardBody(
    useShinyjs(),
    tabItems(
      tabItem("dashboard", "Dashboard tab content"),
      tabItem("widgets", "Widgets tab content"),
      tabItem("hiddenCharts", "Charts Tab"),
      tabItem("subitem1", "Sub-item 1 tab content"),
      tabItem("subitem2", "Sub-item 2 tab content") 
    )
  )
)

server <- function(input, output, session) {
  observeEvent(input$sidebarItemExpanded, {
    if(input$sidebarItemExpanded == "CHARTS"){
      updateTabItems(session, "sidebarID", selected = "hiddenCharts")
    }
  })
}

shinyApp(ui, server)

result

PS: Here and here related GitHub issues can be found.

If you want to expand / collapse menuItem's in the sidebar when using updateTabItems please check this.
