shiny: start the app with hidden tabs, with NO delay

Question

I would like to build an application and some of the tabs will be hidden to the user until he types the right password. I know how to do this with shinyjs::hideTab

Answer 1

How about this

library(shiny);library(shinyjs)
ui <- fluidPage(useShinyjs(),
                navbarPage("hello", id="hello",
                           tabPanel("home", br(), h3("this is home"),passwordInput("pass", "enter 'password' to see the tabs: "),actionButton("enter", "enter")),
                           tabPanel("tab2",uiOutput("tab2Content")),
                           tabPanel("tab3 with a lot of stuff in it", uiOutput("tab3Content"))))
server <- function(input, output, session) {
  output$tab2Content <- renderUI({
    req(input$pass == "password")
    tagList(
      br(), 
      h4("this is tab2")
    )
  })
  output$tab3Content <- renderUI({
    req(input$pass == "password")
    tagList(
      br(), 
      h4("this is tab3")
    )
  })}
shinyApp(ui, server)

hope this helps!
