Shiny: Open new dashboard with actionButton - r

Question

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)
