In essence, I would like to replace the icon in each menuItem() in a shinydashboard with an image. More specifically, I just need each menuItem() to have an image then text next to it.
Here's some moderately successful attempts I have tried (commented in code below);
library(shiny)
library(shinydashboard)
ui <- dashboardPage(
dashboardHeader(title = "Dashboard MenuItems"),
dashboardSidebar(
sidebarMenu(
id = "tabs",
menuItem(
"Dashboard",
tabName = "dashboard",
## creates a drop down w/ no image
# label = img(src = "logo.png",
# title = "logo", height = "35pt")
## creates a drop down with the images
# `tag$` isn't needed
# tags$img(src = "logo.png",
# title = "logo", height = "35pt")
),
menuItem(
"Not Dashboard",
tabname = "not_dashboard"
)
) # end sidebarMenu
), # end dashboardSidebar
dashboardBody(
fluidRow(
box(
title = "stuff goes here",
width = 12
)
)
) # end dashboardBody
)
server <- function(input, output, session) {
message("You can do it!")
}
shinyApp(ui, server)
I successfully used action buttons with background images to simulate the behavior, but I would prefer to find a solution using menuItem()s, if possible.
I was hoping there would be a similar method to add the image to the background of the menuItem() or concatenate the image with the text within the menuItem().
I am not good with shiny tags. I don't really know much about HTML/CSS/JS or Bootstrap, most of the time I can find a solution here and hack my way to what I want, but this one has eluded me.
Any ideas?
You can keep your images in the www folder and use a div to wrap the image along with the text as shown below.
ui <- dashboardPage(
dashboardHeader(title = "Dashboard MenuItems"),
dashboardSidebar(
sidebarMenu(
id = "tabs",
menuItem( div(tags$img(src = "YBS.png", width="20px"), "Dashboard2"),
tabName = "dashboard" # , icon=icon("b_icon")
),
menuItem(
div(tags$img(src = "mouse.png", width="35px"),"Not Dashboard"),
tabname = "not_dashboard" #, icon=icon("home")
)
) # end sidebarMenu
), # end dashboardSidebar
dashboardBody(
fluidRow(
box(
title = "stuff goes here",
width = 12
)
)
) # end dashboardBody
)
server <- function(input, output, session) {
message("You can do it!")
}
shinyApp(ui, server)

I have a shiny app with popovers that contain useful information on interpretation of plot output. However, i have to close the popover "manually" everytime. Otherwise the popover of tab "dash1" will stay even if i switch to tab "dash2".
library(shiny)
library(bs4Dash)
ui <- dashboardPage(
dashboardHeader(title = "Dashboard",
titleWidth = 550,
disable= FALSE,
sidebarIcon = NULL
),
dashboardSidebar(
sidebarMenu(
menuItem("dash1", tabName= "dashboard1"),
menuItem("dash2", tabName= "dashboard2")
)
),
dashboardBody(
tabItems(
tabItem(tabName = "dashboard1",
box(
title = "Interpretation",
popover(
actionButton("goButton", "Click here"),
title = "Important information",
placement = "right",
content = "popover text bla bla"
)
)
),
tabItem(tabName = "dashboard2",
box(
title = "Interpretation",
popover(
actionButton("goButton2", "Click here"),
title = "Important information",
placement = "right",
content = "popover text bla bla"
)
)
)
)
)
)
server <- function(input, output) {
}
shinyApp(ui = ui, server = server)
How can i prevent this "behavior"? Do i necessarily have to specify addPopover and removePopover within the server part?
I solved the problem with the help of this issue:
Display Text only on hover
What i need is a tooltip rather than a popover.
I am creating a sidebar menu from the Server of my Shiny app, but the formatting of the server-generated menu doesn't match with the menu created in the UI.
I have tried some shinyjs hide/show functions after assigning a div() to the menu which also ends up with an odd, non-matching format. I think renderMenu is probably the better path. I would prefer not to 'hack' with CSS, but any help is appreciated.
Here's a working script:
library(shiny)
library(shinydashboard)
ui <- dashboardPage(
dashboardHeader(title = 'Header'),
dashboardSidebar(
sidebarMenu(
menuItem('First Menu', tabName = 'first_menu'),
menuSubItem('sub1', tabName = 'sub_1'),
menuSubItem('sub2', tabName = 'sub_2'),
uiOutput('server_menu')
)
),
dashboardBody()
)
server <- function(input, output) {
output$server_menu <- renderMenu({
list(
menuItem('Second Menu', tabName = 'second_menu'),
menuSubItem('sub3', tabName = 'sub_3'),
menuSubItem('sub4', tabName = 'sub_4')
)
})
}
shinyApp(ui, server)
Which produces this result:
Any advice on how I can solve this would be awesome! Cheers
Instead of uiOutput, use menuItemOutput. Also, your hierarchy of menuItem and menuSubItem seems to be incorrect. menuSubItem should be child of menuItem
library(shiny)
library(shinydashboard)
ui <- dashboardPage(
dashboardHeader(title = 'Header'),
dashboardSidebar(
sidebarMenu(
menuItem(
'First Menu',
tabName = 'first_menu',
menuSubItem('sub1', tabName = 'sub_1'),
menuSubItem('sub2', tabName = 'sub_2')
),
menuItemOutput('server_menu') # Changed from uiOuput to menuItemOutput
)
),
dashboardBody()
)
server <- function(input, output) {
output$server_menu <- renderMenu({
list(
# modified hierarchies
menuItem(
'Second Menu',
tabName = 'second_menu',
menuSubItem('sub3', tabName = 'sub_3'),
menuSubItem('sub4', tabName = 'sub_4')
)
)
})
}
shinyApp(ui, server)
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)
There is a wrong display in shiny dashboard for the below code. The title "Yet to do" is getting displayed as soon as i run the app. I need that when I click on Bivariate Analysis. What is the issue here. This happened when I introduced selectinput under menu item. Earlier it was working well
library(shinydashboard)
library(shiny)
ui <- dashboardPage(
dashboardHeader(title = "Data Analysis"),
dashboardSidebar(
sidebarMenu(
menuItem("Univariate Analysis", tabName = "Univariate", icon =
icon("question"),selectInput("Factors",h5("Factors"),choices =
c("","A","B"))),
menuItem("Bivariate Analysis", tabName = "Bivariate", icon =
icon("question")))
),
dashboardBody(
tabItems(
tabItem(tabName = "Univariate",fluidRow(box(plotOutput("Plot1"),width =
1000,height = 1000),
box(plotOutput("Plot2"),width =
1000,height = 1000))),
tabItem(tabName = "Bivariate",h1("Yet to do")))
))
server <- function(input, output) {
}
shinyApp(ui, server)
It is related having selectInput() as menuItem(). I tried some options like creating menuSubItem etc. but couldn't get it to work. This is probably some bug so you may have to look around for a fix. For now, I'd suggest moving the selectInput inside dashboardBody() -
ui <- dashboardPage(
dashboardHeader(title = "Data Analysis"),
dashboardSidebar(
sidebarMenu(
menuItem("Univariate Analysis",
tabName = "Univariate", icon = icon("question")
# removing selectInput from here fixes the issue
# ,selectInput("Factors", h5("Factors"), choices = c("","A","B"))
),
# an option is to have selectInput by itself but probably not the layout you want
# selectInput("Factors", h5("Factors"), choices = c("","A","B")),
menuItem("Bivariate Analysis",
tabName = "Bivariate", icon = icon("question")
)
)
),
dashboardBody(
tabItems(
tabItem(tabName = "Univariate",
fluidRow(
# add selectInput somewhere on Univariate page
selectInput("Factors", h5("Factors"), choices = c("","A","B")),
box(plotOutput("Plot1"), width = "50%", height = "50%"),
box(plotOutput("Plot2"), width = "50%", height = "50%")
)
),
tabItem(tabName = "Bivariate",
h1("Yet to do")
)
)
)
)
server <- function(input, output) {}
shinyApp(ui, server)
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)
