对于闪亮仪表板的特定选项卡，完全禁用右侧边栏功能 [英] Disable right sidebar ability at all for a specific tab of a shiny dashboard

问题描述

我下面有一个闪闪发光的仪表板，我想知道是否有办法在选择特定选项卡时默认隐藏左右侧栏。在这种情况下，制表符'Front'。我用shinyJs()做到了这一点。有没有办法也隐藏'gear'图标，以及完全不让"Front"打开右侧边栏的能力？更具体地说，当用户在Front选项卡中时，当他单击右上角的gear图标时，应该根本不可能启用右侧边栏显示。此选项卡没有右侧栏，因为它是空的且无用。

## app.R ##
        library(shiny)
        library(shinydashboard)
        library(shinydashboardPlus)
        library(DT)
        library(shinyWidgets)
        library(shinyjs)
        ui <- dashboardPagePlus(
            dashboardHeaderPlus(
                enable_rightsidebar = TRUE,
                rightSidebarIcon = "gears",
                fixed = T
            ),

            dashboardSidebar(
            ),

            dashboardBody(
                useShinyjs(),
                tags$hr(),
                tabsetPanel(
                    id ="tabA",
                    type = "tabs",
                    tabPanel("Front",icon = icon("accusoft")),
                    tabPanel("Data", icon = icon("table")


                    )
                )
            ),
            rightsidebar = rightSidebar(

            )
        )

        server <- function(input, output) {
            observe({
               if (input$tabA == "Front") {
                   addClass(selector = "body", class = "sidebar-collapse")
                   removeClass(selector = "body", class = "control-sidebar-open")
               } else {
                   removeClass(selector = "body", class = "sidebar-collapse")
                   addClass(selector = "body", class = "control-sidebar-open")
               }
            })
        }

        shinyApp(ui = ui, server = server)

推荐答案

请参阅以下内容：

## app.R ##
library(shiny)
library(shinydashboard)
library(shinydashboardPlus)
library(DT)
library(shinyWidgets)
library(shinyjs)

ui <- dashboardPagePlus(
  dashboardHeaderPlus(
    enable_rightsidebar = TRUE,
    rightSidebarIcon = "gears",
    fixed = T
  ),
  dashboardSidebar(),
  dashboardBody(
    useShinyjs(),
    tags$hr(),
    tabsetPanel(
      id ="tabA",
      type = "tabs",
      tabPanel("Front",icon = icon("accusoft")),
      tabPanel("Data", icon = icon("table")
      )
    )
  ),
  rightsidebar = rightSidebar()
)

server <- function(input, output) {
  observe({
    if (input$tabA == "Front") {
      hide(selector = "body > div.wrapper > header > nav > div:nth-child(4) > ul")
      addClass(selector = "body", class = "sidebar-collapse")
      removeClass(selector = "body", class = "control-sidebar-open")
    } else {
      show(selector = "body > div.wrapper > header > nav > div:nth-child(4) > ul")
      removeClass(selector = "body", class = "sidebar-collapse")
      addClass(selector = "body", class = "control-sidebar-open")
    }
  })
}

shinyApp(ui = ui, server = server)
