问题
I am trying to create this dashboard with following structure. It basic structure has 3 levels (Menu, sub Menu and radioGroupButton selection) SideBar: Menu1: has 2 sub menus (Sub Menu 1 and Sub Menu2) Menu2 has 2 sub menus (Sub Menu 3 and Sub Menu4) The body has radioGroupButton that has 2 choices
dashBoardBody: RadioGroupButton: Choice 1 and Choice 2
So when the user clicks Sub Menu1 and clicks Choice 1 then I need to display #A1 Sub Menu1 and clicks Choice 2 then I need to display #A2
Sub Menu2 and clicks Choice 1 then I need to display #A3 Sub Menu2 and clicks Choice 2 then I need to display #A4 Likewise for sub menu 3 and 4.
I want #A1...A8 to hide or display based on the selection on Choice 1 or Choice 2. I didnt know how to show or hide the fluidRows (#A1- #A8). Please advise.
`shinyApp(
ui= dashboardPagePlus(skin="purple-light",dashboardHeader(title="Testing"),
dashboardSidebar(width=200,
sidebarMenu(
menuItem("Menu1", tabName = "dashboard",startExpanded = TRUE,
menuSubItem("Sub Menu1", tabName = "sub1"),
menuSubItem("Sub Menu2", tabName = "sub2")),
menuItem("Menu2", tabName= "Widgets",startExpanded = TRUE,
menuSubItem("Sub Menu3", tabName = "sub3"),
menuSubItem("Sub Menu4", tabName = "sub4")))),
dashboardBody(radioGroupButtons("rb1",label=NULL, choices = c("choice1","choice2"), selected=
"choice1",individual= TRUE,status="info", justified= TRUE ,direction= "horizontal"),
tabItems(
tabItem("sub1",title= "Tab1",
fluidRow(plotOutput("plotgraph1")), #A1
fluidRow(plotOutput("plotgraph2"))), #A2
tabItem("sub2", title= "Tab2",
fluidRow(plotOutput("plotgraph3")), #A3
fluidRow(plotOutput("plotgraph1"))), #A4
tabItem("sub3", title= "Tab3",
fluidRow(plotOutput("plotgraph3")), #A5
fluidRow(plotOutput("plotgraph2"))), #A6
tabItem("sub4", title= "Tab4",
fluidRow(plotOutput("plotgraph1")), #A7
fluidRow(plotOutput("plotgraph1")) )))), #A8
server = function(input,output){
set.seed(1234)
pt1 <- qplot(rnorm(500),fill=I("red"),binwidth=0.2,title="plotgraph1")
pt3 <- qplot(rnorm(600),fill=I("blue"),binwidth=0.2,title="plotgraph3")
pt2 <- reactive({input$rb1
if (input$rb1 =="choice1"){
return(qplot(rnorm(500),fill=I("blue"),binwidth=0.2,title="plotgraph2"))
} else {
return(NULL)
}
})
output$plotgraph1 = renderPlot({pt1})
output$plotgraph2 = renderPlot({pt2()})
output$plotgraph3 = renderPlot({pt3})
})
)`

For demonstration purpose, I have implemented for one sub-menu. You can expand to others similarly. You were very close.
The following code:
ui <- dashboardPage(#skin="purple-light",
dashboardHeader(title="Testing"),
dashboardSidebar(width=200,
sidebarMenu(
menuItem("Menu1", tabName = "dashboard",startExpanded = TRUE,
menuSubItem("Sub Menu1", tabName = "sub1"),
menuSubItem("Sub Menu2", tabName = "sub2")),
menuItem("Menu2", tabName= "Widgets",startExpanded = TRUE,
menuSubItem("Sub Menu3", tabName = "sub3"),
menuSubItem("Sub Menu4", tabName = "sub4")))),
dashboardBody(radioGroupButtons("rb1",label=NULL, choices = c("choice1","choice2"), selected=
"choice1",individual= TRUE,status="info", justified= TRUE ,direction= "horizontal"),
tabItems(
tabItem("sub1",title= "Tab1",
#fluidRow(plotOutput("plotgraph1")), #A1
fluidRow(plotOutput("plotgraph2"))) #A2
# tabItem("sub2", title= "Tab2",
# fluidRow(plotOutput("plotgraph3")), #A3
# fluidRow(plotOutput("plotgraph1"))), #A4
#
# tabItem("sub3", title= "Tab3",
# fluidRow(plotOutput("plotgraph3")), #A5
# fluidRow(plotOutput("plotgraph2"))), #A6
#
# tabItem("sub4", title= "Tab4",
# fluidRow(plotOutput("plotgraph1")), #A7
# fluidRow(plotOutput("plotgraph1")) ) #A8
))) #A8
server <- function(input,output){
set.seed(1234)
pt1 <- qplot(rnorm(500),fill=I("red"),binwidth=0.2,title="plotgraph1")
pt3 <- qplot(rnorm(600),fill=I("blue"),binwidth=0.2,title="plotgraph3")
pt2 <- reactive({
req(input$rb1)
if (input$rb1 =="choice1"){
return(qplot(rnorm(500),fill=I("blue"),binwidth=0.2,title="plotgraph1"))
}else if (input$rb1 =="choice2") {
return(qplot(rnorm(500),fill=I("red"),binwidth=0.2,title="plotgraph2"))
}else {return(NULL)}
})
output$plotgraph1 = renderPlot({pt1})
output$plotgraph2 = renderPlot({pt2()})
output$plotgraph3 = renderPlot({pt3})
}
shinyApp(ui, server)
gives this output:
You can add the skin and expand it. Also, yes, you can add a bunch of items in a given tab. For example, you can output a plot, datatable, uiOutput, etc., as shown below.
tabPanel("Plot", value="tab3",
plotlyOutput("plot11", height=750),
DT::dataTableOutput("testtable3")
uiOutput("saveplotsbtn1"))
