Is there a way to include an absolute panel like in this example (https://shiny.rstudio.com/gallery/superzip-example.html) to a flexdashboard (on a leaflet) ? The idea would be to have a mobile panel dedicated to the leaflet output instead of a sidebar panel.
The absolute panel example here based on a shiny example (with ui and server parts)
library(shiny)
ui <- shinyUI(bootstrapPage(
absolutePanel(
id = "controls", class = "panel panel-default", fixed = TRUE,
draggable = TRUE, top = 60, left = "auto", right = 20, bottom = "auto",
width = 330, height = "auto",
HTML('<button data-toggle="collapse" data-target="#demo">Collapsible</button>'),
tags$div(id = 'demo',
checkboxInput('input_draw_point', 'Draw point', FALSE ),
verbatimTextOutput('summary')))
))
server <- shinyServer(function(input, output, session) {
output$summary <- renderPrint(print(cars))
})
shinyApp(ui = ui, server = server)
a code example below for the Flexdashboard part :

Try this.

runtime: shiny on the top, otherwise, you can delete this line.reactive as the simplest server part. If you want to use a more complex server (logic), e.g. several components interact together, you need to write the actual server function. I would suggest just write a shiny app instead of a flexdashboard. container-fluid class which with this can allow you to drag the panel. There may be a way to work around, you can search for it. Look at the last chunck, I inserted a actual shiny app and the panel is draggable. You should see two tabs when you run the doc, watch the difference. So, if you really want to drag this panel, you should write a "real" shiny app.
