I am working in an application similar to one below. I have my input panel in sidebar under a menu which is initally expanded. I want to collapse the menu and hide all the input panel so that my sidebar will be clean. But It should appear when I expand (not permanently hide). I tried the following solution but it is not working. Please help me to find a solution or any alternative approach.
library(shiny)
library(shinydashboard)
library(shinyjs)
ui <- dashboardPage(
header = dashboardHeader(),
sidebar = dashboardSidebar(
sidebarMenu(
menuItem(
startExpanded = TRUE,
"Menu 1",
column(
width = 12,
actionButton("hideMe", label = "Collapse Me", icon = icon("close"))
)
)
)
),
body = dashboardBody()
)
server <- function(input, output, server){
observeEvent(input$hideMe, {
shinyjs::hide(selector = "ul.menu-open");
})
}
runApp(shinyApp(ui, server))
You need to add useShinyjs() into ui part
library(shiny)
library(shinydashboard)
library(shinyjs)
ui <- dashboardPage(
header = dashboardHeader(),
sidebar = dashboardSidebar(
useShinyjs(),
sidebarMenu(
menuItem(
startExpanded = TRUE,
"Menu 1",
column(
width = 12,
actionButton("hideMe", label = "Collapse Me", icon = icon("close"))
)
)
)
),
body = dashboardBody()
)
server <- function(input, output, server){
observeEvent(input$hideMe, {
shinyjs::hide(selector = "ul.menu-open");
})
}
runApp(shinyApp(ui, server))

I have the shiny dashboard below and as you see I want to display a datatable inside sidebar but the issue is that the table is much wider. Can I make the table fit in exactly in the sidebar without increasing sidbar width?
library(shiny)
library(shinydashboard)
library(DT)
ui <- dashboardPage(
dashboardHeader(),
dashboardSidebar(
sidebarMenu(
menuItem("Table" , tabname = "my_table", icon = icon("table"),DT::dataTableOutput("example_table")
),
menuItem("Next Widget", tabName = "Other"))),
dashboardBody(
tabItems(
tabItem(tabName = "subMenu", #my_table",
fluidRow(
)),
tabItem(tabName = "Other",
h2("Other tab")
)
)))
server <- function(input, output) {
output$example_table <- DT::renderDataTable(head(mtcars))
}
shinyApp(ui, server)
One quick way is to enable horizontal scrolling for your DT. Then the table will fit the container but be scrollable:
library(shiny)
library(shinydashboard)
ui <- dashboardPage(
dashboardHeader(),
dashboardSidebar(
sidebarMenu(
menuItem("Table" , tabname = "my_table", icon = icon("table"),DT::dataTableOutput("example_table")
),
menuItem("Next Widget", tabName = "Other"))),
dashboardBody(
tabItems(
tabItem(tabName = "subMenu", #my_table",
fluidRow(
)),
tabItem(tabName = "Other",
h2("Other tab")
)
)))
server <- function(input, output) {
output$example_table <- DT::renderDataTable(head(mtcars), options = list(scrollX=TRUE))
}
shinyApp(ui, server)
I want to put a dropdown menu on shinydashboard header for dashboard theme change. My shiny app is like below. I could not make the app work. What I got is error message;
Error in FUN(X[[i]], ...) : Expected tag to be of type li
It seems like the dashboard area does not accept those typical shiny widgets? The header area is the best place to put this functionality. Does anyone know how I can make that work? Thanks a lot.
library(shiny)
library(shinydashboard)
library(shinyWidgets)
library(dashboardthemes)
header <- dashboardHeader(
title = "Dashboard Demo",
dropdownButton(
tags$h3("List of Themes:"),
radioButtons(inputId = 'theme',
label = 'Dashboard Theme',
choices = c('blue_gradient', 'boe_website', 'grey_light','grey_dark',
'onenote', 'poor_mans_flatly', 'purple_gradient'),
selected = 'grey_dark',
inline=FALSE),
circle = TRUE, status = "primary",
icon = icon("window-maximize"), width = "300px",
tooltip = tooltipOptions(title = "Click to change dashboard theme")
)
)
shinyApp(
ui = dashboardPage(
header,
dashboardSidebar(),
dashboardBody(
shinyDashboardThemes(
theme = input$theme
),
)
),
server = function(input, output) { }
)
You can not put the dropdownButton in the dashboardHeader.
Instead you can put it in the dashboardBody or dashboardSidebar and have it updated like this :
library(shiny)
library(shinydashboard)
library(shinyWidgets)
library(dashboardthemes)
shinyApp(
ui = dashboardPage(
dashboardHeader(title = "Dashboard Demo"),
dashboardSidebar(),
dashboardBody(
dropdownButton(
radioButtons(inputId = 'theme',
label = 'Dashboard Theme',
choices = c('blue_gradient', 'boe_website', 'grey_light','grey_dark',
'onenote', 'poor_mans_flatly', 'purple_gradient'))
),
uiOutput("myTheme")
)
),
server = function(input, output) {
output$myTheme <- renderUI( shinyDashboardThemes(theme = input$theme))
}
)
I would like to open a second dashboard by pressing the action button on the first dashboard. I was able to do that using the code below but the dashboards are connected to each other. E.g. if I close the sidebar on the second dashboard, the sidebar of the first one closes, too.
This is the server.R file:
function(input, output, session) {
# some more code
# react to clicking on button show2
observeEvent(input$show2, {
# here is some more code
showModal(settngsModal())
})
settngsModal <- function() {
modalDialog(
withTags({
dashboardPage(
dashboardHeader(
title = "Second Dashboard"
),
dashboardSidebar(
sidebarMenu(
menuItem("Widgets", tabName = "widgets", icon = icon("th"))
)),
dashboardBody(
tabItem(tabName = "widgets",
h1("Widgets tab content")
)
)
)
}),
title = "Settings",
fade = TRUE)
}
}
This is the ui.R file:
dashboardPage(
dashboardHeader(
title = "First dashboard"
),
dashboardSidebar(collapsed = TRUE,sidebarMenu()),
dashboardBody(),
h1('Headline'),
actionButton("show2", "Show second dashboard", size = 'lg')
)
)
Is it possible to have an "independent" dashboard?
Maybe even having two dashboards that can be used side by side (because now the second dashboard is a popup and the first dashboard can only be used if the second one is closed)?
You could use shinyjs to toggle between the two dashBoardPage tags.
Below is an example of switching between two Dashboards, there's a decent issue thread around rendering UI dashboardPage elements reactively.
library(shiny)
library(shinydashboard)
library(shinyjs)
ui <- tagList(
useShinyjs(),
div(id = "dashboard_two",
style = "display:none",
dashboardPage(
dashboardHeader(
title = "Second dashboard"
),
dashboardSidebar(collapsed = TRUE,sidebarMenu()),
dashboardBody(fluidRow(actionButton("show1", "Show first dashboard")),
fluidRow(box(title = "Dash Two", height = 300, "Testing Render")) )
)
),
div(id = "dashboard_one",
style = "display:none",
dashboardPage(
dashboardHeader(
title = "First dashboard"
),
dashboardSidebar(collapsed = TRUE, sidebarMenu()),
dashboardBody(actionButton("show2", "Show second dashboard")
)
)
)
)
server <- function(input, output) {
shinyjs::show("dashboard_one")
observeEvent({ input$show1; input$show2}, {
shinyjs::toggle("dashboard_one")
shinyjs::toggle("dashboard_two")
})
}
shinyApp(ui, server)
I am trying to render shinydashboard after login page but shinydashboard skin color is not showing.
my code is as follow:
ui.r
library(shinydashboard)
library(shiny)
uiOutput("page")
Login.R
library(shinydashboard)
ui1Output <- function(id, label = "ui1") {
shinyUI(fluidPage(
mainPanel(
textInput("username","Username",placeholder ="UserName"),
passwordInput("password","Password", placeholder ="Password"),
actionButton("login", "Login")
)))
}
dashbaordpage.R
library(shinydashboard)
dashpageOutput <- dashboardPage(
dashboardHeader(title = "Basic dashboard"),
dashboardSidebar(
sidebarMenu(
menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
menuItem("Widgets", tabName = "widgets", icon = icon("th"))
)
),
dashboardBody(
tabItems(
# First tab content
tabItem(tabName = "dashboard",h2("Dashbaord")),
# Second tab content
tabItem(tabName = "widgets",
h2("Widgets tab content")
)
)
)
global.R
source('login.R') #login page
source('dashboardPage.R')#dashbaordpage
server.R
library(shiny)
library(shinydashboard)
shinyServer(function(input, output,session) {
output$page <- renderUI({
ui1Output('ui1Output')
})
observeEvent(input$login,
{
if(True)
{
output$page <- renderUI(dashpageOutput)
}
else
{
Logged<-F
showModal(modalDialog(
title = "Error",
"Enter Correct Username and password"
))
}
})
})
Details: when I going dashboard is showing but not with default skin color or any other skin color. I have tried skin='red' like wise option.
Image for reference how actually showing after login.
Please help me.
Thanks in advance.
I am using shinydashboard to create the interface of my shiny App. However I want one input which appear in the two tabMenu. In the example below, I want to textInput i_test appears in menu menu1 and menu2.
How should I implement it? Thanks for any suggestions.
library(shiny)
library(shinydashboard)
# Side bar boardy
sidebar <- dashboardSidebar(
sidebarMenu(
id = 'menu_tabs'
, menuItem('menu1', tabName = 'menu1')
, menuItem('menu2', tabName = 'menu2')
, menuItem('menu3', tabName = 'menu3')
)
)
# Body board
body <- dashboardBody(
tabItems(
tabItem(
tabName = 'menu1',
textInput('i_test', 'Test')
),
tabItem(
tabName = 'menu2'
)
)
)
# Shiny UI
ui <- dashboardPage(
title = 'test',
dashboardHeader(),
sidebar,
body
)
server <- function(input, output, session) {
}
shinyApp(ui, server)
It seems that shiny always renders two distinct elements, even if you try to build the same element a second time.
Thats why i could only come up with a solution that only makes it look like the two text iputs are the same.
Check the Code:
library(shiny)
library(shinydashboard)
# Side bar boardy
sidebar <- dashboardSidebar(
sidebarMenu(
id = 'menu_tabs'
, menuItem('menu1', tabName = 'menu1')
, menuItem('menu2', tabName = 'menu2')
, menuItem('menu3', tabName = 'menu3')
)
)
# Body board
body <- dashboardBody(
tabItems(
tabItem(
tabName = 'menu1',
textInput('i_test_1', 'Test')
),
tabItem(
tabName = 'menu2',
textInput('i_test_2', 'Test')
),
tabItem(
tabName = 'menu3'
)
)
)
# Shiny UI
ui <- dashboardPage(
title = 'test',
dashboardHeader(),
sidebar,
body
)
server <- function(input, output, session) {
observe({
text1 <- input$i_test_1
updateTextInput(session, 'i_test_2', value = text1)
})
observe({
text2 <- input$i_test_2
updateTextInput(session, 'i_test_1', value = text2)
})
}
shinyApp(ui, server)
