Issue is I want to populate sidebar menuItem with a list. However, I have to click on the Click to Load CWE Titles" menuItem, then click any other menuItem for it to populate.
I want to be able to hide the list:
library(shinydashboard)
cwetitles <- c("criosphinx","bibliophilic","billing","rudolf",
"overromanticizing","nonunderstandable","carboniferous","wan",
"calcanei","inimically","unenlivening","scissure","flamboyantly",
"hypotonicity","impressionableness","coligny","attender",
"perspective","enumclaw","diddicoy")
ui <- dashboardPage(
dashboardHeader(title ="CVE Reporting Dashboard", titleWidth = 350),
dashboardSidebar(
sidebarMenu(id = "tabs",
menuItem("Overview", tabName="summary", icon=icon("info-circle")),
menuItem("Dashboard", tabName = "dashboard", icon=icon("dashboard")),
menuItem("Charts", tabName = "charts", icon = icon("bar-chart-o")),
menuItem("Click to View CVE Category", icon = icon("info-circle"),
menuSubItem("General CVEs",icon=icon("th"),tabName ="cvetable"),
menuSubItem("Web Applications CVEs",icon=icon("th"),tabName ="WASC")
),
actionButton(inputId="clearAll", label="Clear selection", icon=icon("square-o"),style="color:#fff; background-color:#337ab7; border-color: #2e6da4"),
actionButton(inputId="selectAll", label="Select all", icon=icon("check-square-o"),style="color:#fff; background-color: #337ab7; border-color: #2e6da4"),
menuItem("Click to Load CWE Titles",tabName = "cwetitlesControl", icon = icon("th"), uiOutput("cwetitlesControl"), selected = TRUE)
)
),
dashboardBody(
tabItems(
tabItem(tabName = "summary",includeMarkdown("about.md"))
)
)
)
server <- function(input, output) {
# use a reactive value to represent group level selection
values <- reactiveValues()
values$cwetitles <- cwetitles
# Create event type checkbox
output$cwetitlesControl <- renderUI({
withProgress(message = 'Calculation in progress',
detail = 'This may take a while...', value = 0, {
for (i in 1:15) {
incProgress(1/15)
Sys.sleep(0.25)
}
})
checkboxGroupInput('cwetitles', 'CWE Titles:',choices = cwetitles, selected = values$cwetitles)
})
}
shinyApp(ui, server)
Thanks to #rosscova for providing some direction. This is the solution i came up with and it works.
library(shinydashboard)
cwetitles <- c("criosphinx","bibliophilic","billing","rudolf",
"overromanticizing","nonunderstandable","carboniferous","wan",
"calcanei","inimically","unenlivening","scissure","flamboyantly",
"hypotonicity","impressionableness","coligny","attender",
"perspective","enumclaw","diddicoy")
ui <- dashboardPage(
dashboardHeader(title ="CVE Reporting Dashboard", titleWidth = 350),
dashboardSidebar(
sidebarMenu(id = "tabs",
menuItem("Overview", tabName="summary", icon=icon("info-circle")),
menuItem("Dashboard", tabName = "dashboard", icon=icon("dashboard")),
menuItem("Charts", tabName = "charts", icon = icon("bar-chart-o")),
menuItem("Click to View CVE Category", icon = icon("info-circle"),
menuSubItem("General CVEs",icon=icon("th"),tabName ="cvetable"),
menuSubItem("Web Applications CVEs",icon=icon("th"),tabName ="WASC")
),
actionButton(inputId="clearAll", label="Clear selection", icon=icon("square-o"),style="color:#fff; background-color:#337ab7; border-color: #2e6da4"),
actionButton(inputId="selectAll", label="Select all", icon=icon("check-square-o"),style="color:#fff; background-color: #337ab7; border-color: #2e6da4"),
menuItem("Click to Load CWE Titles",tabName = "cwetitlesControl",
icon = icon("th"), checkboxGroupInput('cwetitles',
'CWE Titles:',
choices = cwetitles,
selected = cwetitles), selected = TRUE)
)
),
dashboardBody()
)
server = function(input, output, session) {
values <- reactiveValues()
values$cwetitles <- cwetitles
observe({
if(input$selectAll == 0) return()
updateCheckboxGroupInput(session,'cwetitles','CWE Titles:',
choices = cwetitles,
selected = values$cwetitles)
#values$cwetitles <- cwetitles
})
observe({
if(input$clearAll == 0) return()
updateCheckboxGroupInput(session,'cwetitles','CWE Titles:',
choices = cwetitles,
selected = c())
#values$cwetitles <- NULL # empty list
})
}

I have the shiny app below in which I would like to set the name of the second menuItem() by typing in the textInput() of the first menuItem(). And then move to it by clicking an actionButton(). Also why the textOutput() I use is dispalyed under the icon and not next it like the first one?
## app.R ##
library(shiny)
library(shinydashboard)
ui <- dashboardPage(
dashboardHeader(
),
dashboardSidebar(
collapsed = TRUE,
sidebarMenu(
id="inTabset",
menuItem("Workspace", tabName = "workspace", icon = icon("upload")),
menuItemOutput("tab2")
)
),
dashboardBody(
tabItems(
# First tab content
tabItem(tabName = "workspace",
fluidRow(
textInput("name", "", value = "Process model", placeholder = NULL),
actionButton("nextt","Next", icon("paper-plane")
)
)
)
),
tabItem(
tabName = "Process model",
)
)
)
server <- function(input, output,session) {
output$tab2 <- renderMenu({
menuItem(text = input$name, tabName = "Process model", icon = icon("diagram-project"))
})
observeEvent(input$nextt, {
updateTabItems(session, "inTabset", selected = "Process model")
})
output$tabtitle <- renderText({
if (input$name == "") {
"Process model"
} else {
paste(input$name)
}
})
observeEvent(input$nextt, {
updateTabItems(session, "inTabset", selected = "Process model")
})
}

To dynamically create and name a menuItem you could use renderMenu and menuItemOutput.
library(shinydashboard)
library(shiny)
ui <- dashboardPage(
dashboardHeader(title = "Basic dashboard"),
dashboardSidebar(
sidebarMenu(
id = "inTabset",
menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
menuItemOutput("tab2")
)
),
dashboardBody(
tabItems(
tabItem(
tabName = "dashboard",
textInput("name", "Create a name for your process", value = "", placeholder = NULL),
actionButton("nextt", "Next")
),
tabItem(
tabName = "widgets"
)
)
)
)
server <- function(input, output, session) {
observeEvent(input$nextt, {
updateTabItems(session, "inTabset", selected = "widgets")
})
output$tab2 <- renderMenu({
menuItem(text = input$name, tabName = "widgets", icon = icon("th"))
})
output$tabtitle <- renderText({
if (input$name == "") {
"Name of process"
} else {
paste(input$name)
}
})
observeEvent(input$nextt, {
updateTabItems(session, "inTabset", selected = "widgets")
})
}

I am trying to clear what ever is written in the text area but looks like it not working. Based on the below applications, when the user clicks on "click" button, the contents (if written) should get cleared. But it is not. Can anyone help me here please........................................
data(mtcars)
library(shiny)
library(shinydashboard)
library(dplyr)
library(DT)
library(shinyjs)
ui <- dashboardPage(
dashboardHeader(title = "Dynamic sidebar"),
dashboardSidebar(sidebarMenu(id = "menu", sidebarMenuOutput("menu"))),
dashboardBody(tabItems
(
tabItem
(tabName = "plots", h2("Dashboard plots"),
fluidRow(column(width = 12, class = "well",
h4("Boxplot"),
plotOutput("bxp")))
),
tabItem(tabName = "dashboard", h2("Dashboard tab content"),
dataTableOutput(outputId = "subdt"),textAreaInput("sd","label1"),textAreaInput("sd1","label2") ,
actionButton("idff","click"))
)
)
)
server <- function(input, output, session) {
output$menu <- renderMenu({
sidebarMenu(
# menuItem("Plots Menu", tabName = "plots", icon = icon("line-chart")),
menuItem("Table Menu", icon = icon("info"),
menuSubItem(
"Dashboard", tabName = "dashboard", icon = icon("calendar")
),
selectInput(
inputId = "mcm", label = "Some label", multiple = TRUE,
choices = unique(mtcars$cyl), selected = unique(mtcars$cyl)
)
)
)
})
observe({
print(input$menu)
})
datsub <- reactive({
mtcars %>%
filter_at(vars("cyl"), all_vars(. %in% input$mcm))
})
output$subdt <- renderDataTable({
datatable(datsub(),selection = if(input$menu == "dashboard"){'single'} else {'none'})
# print(datatable.selection())
})
# datatable(datsub(),selection = if(input$menu == "dashboard"){'single'} else {'none'})
output$bxp <- renderPlot({
hist(rnorm(100))
})
observeEvent(input$idff,{
print("cjec")
shinyjs::reset('sd')
shinyjs::reset('sd1')
})
}
shinyApp(ui, server)
I'd suggest to update the textAreaInput as suggested in the comments. Update the event handler as follows:
observeEvent(input$idff, {
updateTextAreaInput(session = session, inputId = 'sd', value = "")
updateTextAreaInput(session = session, inputId = 'sd1', value = "")
})
I want to hide and show a menuItem when a user check a box. I used useShinyjs() and renderMenu() function but once the menuItem is shown, I cannot hide it again by unchecking the box.
This is what I did :
library(shiny)
library(shinydashboard)
library(shinyjs)
header <- dashboardHeader(title = "my app")
sidebar <- dashboardSidebar(
sidebarMenu(id="menu",
menuItem("Tab 1",tabName = "tab1", icon = icon("question")),
menuItemOutput("another_tab"),
menuItem("Tab 2", tabName = "tab2", icon = icon("home"))
)
)
)
body <- dashboardBody(
tabItems(
tabItem(tabName = "tab1",
useShinyjs(),
checkboxInput("somevalue", "Check me", FALSE)
)
)
)
ui <- dashboardPage(header, sidebar, body)
server <- function(input, output) {
output$another_tab <- renderMenu({
if(input$somevalue == TRUE)
menuItem("My tab", tabName = "tab3", icon = icon("cogs"))
})
}
shinyApp(ui, server)
How can we hide the menuItem again ?
Another way to do it is
output$another_tab <- renderMenu({
if(input$somevalue == TRUE) {
menuItem("My tab", tabName = "tab3", icon = icon("cogs"))
}else shinyjs::hide(selector = "a[data-value='tab3']" )
})
You can create an empty menuItem():
server <- function(input, output) {
output$another_tab <- renderMenu({
if(input$somevalue == TRUE)
menuItem("My tab", tabName = "tab3", id="tab3", icon = icon("cogs"))
else
menuItem(NULL)
})
}
hi i im trying to have the 'choices' in my pickerInput be dependent on what the user types in the search bar above. im using a spotify r package and if you search a certain artist the api returns a table of artists of the similar name and you need to choose which artist you want. anyways i want that table to go into the pickerInput and i can't seem to get it work.
ui <- dashboardPage(skin = "green",
dashboardHeader(title = "Lyric Prediction"),
dashboardSidebar(
sidebarMenu(
menuItem("Overview", tabName = "Overview", icon = icon("search")),
menuItem("Analysis", tabName = "Analysis", icon = icon("bar-chart-o"))
)
),
dashboardBody(
tags$head(
tags$style(HTML(".fa { font-size: 18px; }"))
),
tabItems(
# First tab content
tabItem(tabName = "Overview",
fluidRow(
column(12,
searchInput(
inputId = "search", label = "Search Artist on Spotify",
placeholder = "Search",
btnSearch = icon("search"),
btnReset = icon("remove"),
width = "500px"
)
), align = "center"
),
#HERE - how can i have pickerInput take in the output
#of "res" from the server?
fluidRow(pickerInput(choices = "res")
)),
)
)
server <- function(input, output) {
#function to take search input
#output list of possible artists
output$res <- renderTable({
#Rspotify
possibleArtists <- searchArtist(input$search,token=my_oauth)
possibleArtists <- as_tibble(possibleArtists)
myCols <- c("display_name","id")
colNums <- match(myCols,names(possibleArtists))
possibleArtists <- possibleArtists %>%
select(colNums)
possibleArtists
})
}
shinyApp(ui, server)
Use update method in an observeEvent like this:
observeEvent(input$search, {
#Rspotify
possibleArtists <- searchArtist(input$search,token=my_oauth)
possibleArtists <- as_tibble(possibleArtists)
myCols <- c("display_name","id")
colNums <- match(myCols,names(possibleArtists))
possibleArtists <- possibleArtists %>%
select(colNums)
updatePickerInput(
session = session,
inputId = "picker",
choices = possibleArtists
)
}, ignoreInit = TRUE)
Full example:
library(shiny)
library(shinydashboard)
library(shinyWidgets)
ui <- dashboardPage(
skin = "green",
dashboardHeader(title = "Lyric Prediction"),
dashboardSidebar(
sidebarMenu(
menuItem("Overview", tabName = "Overview", icon = icon("search")),
menuItem("Analysis", tabName = "Analysis", icon = icon("bar-chart-o"))
)
),
dashboardBody(
tags$head(
tags$style(HTML(".fa { font-size: 18px; }"))
),
tabItems(
# First tab content
tabItem(
tabName = "Overview",
fluidRow(
column(12,
searchInput(
inputId = "search", label = "Search Artist on Spotify",
placeholder = "Search",
btnSearch = icon("search"),
btnReset = icon("remove"),
width = "500px"
)
), align = "center"
),
pickerInput(inputId = "picker", label = "Choose an artist:", choices = NULL)
)
)
)
)
server <- function(input, output, session) {
observeEvent(input$search, {
updatePickerInput(
session = session,
inputId = "picker",
choices = c("The Beatles",
"The Beatles Recovered Band",
"Yesterday - A Tribute To The Beatles",
"The Beatles Revival Band & Orchestra")
)
}, ignoreInit = TRUE)

I am trying to build a shiny application using sidebarMenu with menuItems. Currently the menu items are duplicated,
enter image description here
Clicking the first and second menu items are not showing the table or the plot. Only the last two shows the output. How can I modify it to have only two items - 1) Plots Menu, 2) Table Menu (with sub items) and clicking on it show the respective output. Used the mtcars dataset and the code ispasted below
data(mtcars)
ibrary(shiny)
library(shinydashboard)
library(dplyr)
ui <- dashboardPage(
dashboardHeader(title = "Dynamic sidebar"),
dashboardSidebar(
sidebarMenu(
menuItem("Plots Menu", tabName = "plot_page", icon = icon("line-chart")),
menuItem("Table Menu", tabName="intro_page", icon = icon("info"),
selectInput(inputId = "mcm", label = "Some label",
multiple = TRUE, choices = unique(mtcars$cyl), selected = unique(mtcars$cyl)))
),
sidebarMenuOutput("menu")
),
dashboardBody(tabItems(
tabItem(tabName = "plots", h2("Dashboard plots"),
fluidRow(column(width = 12, class = "well",
h4("Boxplot"),
plotOutput("bxp")))
),
tabItem(tabName = "dashboard", h2("Dashboard tab content"),
dataTableOutput(outputId = "subdt"))
)
)
)
server <- function(input, output, session) {
output$menu <- renderMenu({
sidebarMenu(
menuItem("Plots Menu", tabName = "plots", icon = icon("line-chart")),
menuItem("Table Menu", tabName="dashboard", icon = icon("calendar"))
)
})
datsub <- reactive({
mtcars %>%
filter_at(vars("cyl"), all_vars(. %in% input$mcm))
})
output$subdt <- renderDataTable({
datsub()
})
output$bxp <- renderPlot({
hist(rnorm(100))
})
}
shinyApp(ui, server)
I put the code together.

You have both the standard and reactive sidebar options running in tandem. If you need a reactive sidebar, just put the contents in the server function and call all of it with sidebarMenuOutput in ui.
ui.R
dashboardSidebar(sidebarMenu(id = "menu", sidebarMenuOutput("menu")))
server.R
output$menu <- renderMenu({
sidebarMenu(
menuItem("Plots Menu", tabName = "plots", icon = icon("line-chart")),
menuItem("Table Menu", icon = icon("info"),
menuSubItem(
"Dashboard", tabName = "dashboard", icon = icon("calendar")
),
selectInput(
inputId = "mcm", label = "Some label", multiple = TRUE,
choices = unique(mtcars$cyl), selected = unique(mtcars$cyl)
)
)
)
})
