I apologize for the lengthy code sample, but I had to copy an example with tabItems
from the shinydashboard homepage.
Your approach has only few problems. First, if you would inspect the menuItems
, you'd see that the actual tab's id is not tabItem2
, but shiny-tab-tabItem2
. This, plus the extra attribute data-toggle="tab"
within the a
tag would suffice to open the desired tab. Snippet:
a("Computation Completed", href="#shiny-tab-tabItem2", "data-toggle" = "tab")
But, this has its limits. First and most obvious, the state of the menuItem
in the sidebar is not set to active
. This looks very odd and one might not be convinced, that one has been moved to another tab.
Second, and less obvious, if you listen to tab changes (on the server side), you will not get information about this tab switch. Those are triggered by the menuItem
being clicked, and the tab itself will not report if it is visible or hidden.
So, my approach will be to simulate that the corresponding menuItem
is clicked, and thus, all the above problems are solved.
Code example:
library(shiny)
library(shinydashboard)
ui <- shinyUI(
dashboardPage(
dashboardHeader(title = "Some Header"),
dashboardSidebar(
sidebarMenu(
menuItem("Computations", tabName = "tabItem1", icon = icon("dashboard")),
menuItem("Results", tabName = "tabItem2", icon = icon("th"))
)
),
dashboardBody(
tags$script(HTML("
var openTab = function(tabName){
$('a', $('.sidebar')).each(function() {
if(this.getAttribute('data-value') == tabName) {
this.click()
};
});
}
")),
tabItems(
tabItem(tabName = "tabItem1",
fluidRow(
box(plotOutput("plot1", height = 250)),
box(
title = "Controls",
sliderInput("slider", "Number of observations:", 1, 100, 50)
)
),
infoBoxOutput("out1")
),
tabItem(tabName = "tabItem2",
h2("Widgets tab content")
)
)
)
)
)
server <- function(input, output){
histdata <- rnorm(500)
output$plot1 <- renderPlot({
data <- histdata[seq_len(input$slider)]
hist(data)
})
output$out1 <- renderInfoBox({
infoBox("Completed",
a("Computation Completed", onclick = "openTab('tabItem2')", href="#"),
icon = icon("thumbs-o-up"), color = "green"
)
})
}
shinyApp(ui, server)
Note, that the only important thing is the onclick
property, not an href
. This means, that every div
or other element can be used to create this link. You could even have just the thumbs-up image with this onclick
command.
If you have more questions, please comment.

Edit: Whole infoBox clickable.
This is an answer to a comment by OmaymaS. The point was to make the infoBox a clickable container. To achieve this, one can define a new function that makes a somewhat different infoBox. The custom box will be as follows:
customInfoBox <- function (title, tab = NULL, value = NULL, subtitle = NULL, icon = shiny::icon("bar-chart"), color = "aqua", width = 4, href = NULL, fill = FALSE) {
validateColor(color)
tagAssert(icon, type = "i")
colorClass <- paste0("bg-", color)
boxContent <- div(class = "info-box", class = if (fill) colorClass,
onclick = if(!is.null(tab)) paste0("$('.sidebar a')).filter(function() { return ($(this).attr('data-value') == ", tab, ")}).click()"),
span(class = "info-box-icon", class = if (!fill) colorClass, icon),
div(class = "info-box-content",
span(class = "info-box-text", title),
if (!is.null(value)) span(class = "info-box-number", value),
if (!is.null(subtitle)) p(subtitle)
)
)
if (!is.null(href)) boxContent <- a(href = href, boxContent)
div(class = if (!is.null(width)) paste0("col-sm-", width), boxContent)
}
This code is copied from the original infoBox
function definition and only the line with onclick
is new. I also added the openTab
function (with some twitches) right inside the container such that you dont need to worry where to put this function inside the view. Might be a bit overloaded i feel.
This custom info box can be used exactly like the default one and if you pass the additional tab
argument, the link to the sidebar is added.
Edit: Subtitle exploit
As Alex Dometrius mentioned, the use of subtitle
crashes this functionality. This is because the script tag that was inserted, on accident, was used as the subtitle
argument in order to be rendered with the box. To free up this spot, I edited the main example up top such that the script tag is sitting top level in the dashboardBody
(literally anywhere in the ui would be fine).
(To avoid confusion: in Version 1, the tags$script
was supplied inside of infobox
where it was interpreted as the subtitle
parameter.)
