完全禁用发光仪表板特定选项卡的右侧工具栏功能

Question

我下面有一个发光的仪表板，我想知道当选择了一个特定的选项卡时，默认情况下是否有一种方法可以使左侧和右侧边栏保持隐藏状态。在这种情况下，选项卡'Front'。我用shinyJs()做到了。是否有一种方法也可以隐藏'gear'图标和从"Front"完全打开右侧边栏的功能？更具体地说，当用户在Fron t选项卡中时，根本不可能实现单击他在右上角单击gear图标时启用的右侧边栏显示。该选项卡没有空白，因为它是空的并且无用。

        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(

            )
        )

            observe({
               if (input$tabA == "Front") {

## 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")
    }
