Question

我在MenuItem中遇到sidebarMenu的问题。当我添加第三个MenuItem（RFM）时，似乎在ui中将其呈现为一个子项，并且当我单击该项目时，即使在server.R中也没有任何显示。R有相应的功能。这是sidebarMenu的屏幕截图

我希望它已经足够清楚了，请不要降级

Answer 1

您错过了一个大写字母：

  menuItem("RFM",tabname="RFM",icon = icon("dashboard",lib = "glyphicon"))  ## That's the item I ve just added

tabname应该是tabName。

此外，tabItem("RFM",应该是tabItem("rfm",，因为它已链接到id参数中的tabName。

因此，下面给出了一个简化的工作版本-最大限度地减少代码是我发现问题的方式。希望这会有所帮助！

library(shiny)
library(shinydashboard)
library(plotly)

ui <- dashboardPage(
  dashboardHeader(title= "Acquisti Clienti CC"),
  dashboardSidebar(

    sidebarMenu(id="menu",
                menuItem(text = "Dashboard", tabName = "dashboard",icon = icon("stats",lib = "glyphicon")),
                menuItem(text = "Data", tabName = "Data",icon = icon("th-list",lib = "glyphicon")),
                menuItem(text = "RFM", tabName="rfm",icon = icon("th-list",lib = "glyphicon"))
    )
  ),
  dashboardBody(
    tabItems(
      tabItem("dashboard",
              p('dashboard')
      )
      ,
      tabItem("Data",
              p('data')
      ),
      tabItem("rfm",
              p('rfm')
      )
    )
  )
)

server <- function(input,output){}
shinyApp(ui,server)
