当闪亮仪表板中存在menuSubItem时显示menuItem的内容

问题描述

有没有一种方法可以在闪亮的仪表板的内容窗格中实际显示包含现有menuSubItems的menuItem的内容。在示例中：我尝试将"tabName="charts""添加到menuItem"Charts"中，以显示tabItem"charts"的内容。但是，除了打开菜单并显示子菜单(内容窗格仍显示上一选择的"旧"内容)外，没有任何效果：

header <- dashboardHeader()
#> Error in dashboardHeader(): konnte Funktion "dashboardHeader" nicht finden

sidebar <- dashboardSidebar(
  sidebarUserPanel("User Name",
    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")
    )
  )
)
#> Error in dashboardSidebar(sidebarUserPanel("User Name", subtitle = a(href = "#", : konnte Funktion "dashboardSidebar" nicht finden

body <- dashboardBody(
  tabItems(
    tabItem("dashboard",
      div(p("Dashboard tab content"))
    ),
    tabItem("widgets",
      "Widgets tab content"
    ),
    tabItem("subitem1",
      "Sub-item 1 tab content"
    ),
    tabItem("subitem2",
      "Sub-item 2 tab content"
    )
  )
)
#> Error in dashboardBody(tabItems(tabItem("dashboard", div(p("Dashboard tab content"))), : konnte Funktion "dashboardBody" nicht finden

shinyApp(
  ui = dashboardPage(header, sidebar, body),
  server = function(input, output) { }
)
#> Error in shinyApp(ui = dashboardPage(header, sidebar, body), server = function(input, : konnte Funktion "shinyApp" nicht finden

菜单项

很大程度上归功于此问题React to推荐答案()选项卡选择。唯一令人讨厌的是，您必须再次单击Charts选项卡，但我认为这应该没问题

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) { }
)
