Hide and show sidebar panel in shiny

Question

My shiny app has 3 tabPanel in mainPanel, each tabPanel has their own sidebarPanel. I use shinyBS to set sidebarPanel "show and Hide"

bsButton("showpanel", "Show/Hide sidebar",icon = icon("toggle-off"), type = "toggle",style = "info", value = TRUE)

In server

observeEvent(input$showpanel, {
     if(input$showpanel == TRUE) {
      removeCssClass("Main", "col-sm-12")
      addCssClass("Main", "col-sm-8")
      shinyjs::show(id = "Sidebar")
      shinyjs::enable(id = "Sidebar")
    }
    else {
      removeCssClass("Main", "col-sm-8")
      addCssClass("Main", "col-sm-12")
      shinyjs::hide(id = "Sidebar")
    }
  })

I test couple times, 2 tabs work like I expected, but the tab with plots (I use plotly), it appears hiding sidebar but the plots are not automatic stretching out until I click the other tab and go back Plot tab. So if I want to see the plots with full screen, I need to do extra by clicking another tab, and come back.

How do I fix this issue?

Thanks

Next time please post reproducible example...

library(shiny)
library(shinydashboard)
library(plotly)
library(shinyjs)
library(shinyBS)

ui <- dashboardPage(
  dashboardHeader(),
  dashboardSidebar(),
  dashboardBody(
    useShinyjs(),
    extendShinyjs(text = 'shinyjs.hideSidebar = function(params) { $("body").addClass("sidebar-collapse"); 
              $(window).trigger("resize"); }'),
    extendShinyjs(text='shinyjs.showSidebar = function(params) { $("body").removeClass("sidebar-collapse"); 
                  $(window).trigger("resize"); }'),
    bsButton("showpanel", "Show/Hide sidebar",icon = icon("toggle-off"), type = "toggle",style = "info", value = TRUE),
    fluidRow(tabsetPanel(id='tabs',
                         tabPanel(value=1,title="Tab1"),
                         tabPanel(value=2,title="Tab2"),
                         tabPanel(value=3, title="Plot",
                                  fluidRow(
                                    column(12,
                                           plotlyOutput('plot', height=800))))
    )
    )))


server <- function(input, output, session) { 


  output$plot <- renderPlotly({
    plot_ly(data = iris, x = ~Sepal.Length, y = ~Petal.Length)
  })

  observe({
    if(input$showpanel == TRUE) {
      js$showSidebar()
    }
    else {
      js$hideSidebar()
    }
  })
}

shinyApp(ui, server)

One way to do this is to trigger a window resize event when you add/remove the sidebar to force the plot to be redrawn at the right size after the sidebar is shown/hidden. For this purpose i have used:

useShinyjs(),
    extendShinyjs(text = 'shinyjs.hideSidebar = function(params) { $("body").addClass("sidebar-collapse"); 
              $(window).trigger("resize"); }'),
    extendShinyjs(text='shinyjs.showSidebar = function(params) { $("body").removeClass("sidebar-collapse"); 
                  $(window).trigger("resize"); }')

functions.
