How to make the app fill the window?

[rossinerbe]

When I run my app locally it fills the screen showing all the data.
However when I deploy the app, it only takes up a defined area and you have to scroll to see all of the data:

Is there a way to make the pane scale to the size of the window? I have tried FillPage() but that does not work.
Thanks.

Edit to include ReprEx:

list1 = list(matrix(nrow=25, ncol =25), matrix(nrow=25, ncol =25))
names(list1) = c("Choice1", "Choice2")

shinyApp(
  ui = fluidPage(
    tabPanel("tab1", fluid = T,
             sidebarLayout(
               sidebarPanel(
                 selectInput("Input1", "Input1", choices = c("Choice1", "Choice2"))
               ), 
               mainPanel(
                 tableOutput("viewTable")
               )
             )
    )
  ),
  server = function(input, output, session) {
    Data1 <- reactive({
      list1[[input$Input1]]
    })
    
    output$viewTable <- renderTable({
      print(Data1())
    })
  }
)

If I run this app on my local machine when I increase the size of the window the values will fill the pane, whereas when I deploy it with rsconnect::deployApp it remains a static size regardless of window size and has to be scrolled across.

Hi, welcome!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this resources, to see how to create one for a shiny app

Shiny debugging and reprex guide

Shiny issues can be challenging to resolve relative to other problems with your code or statistical methods. Shiny apps are often large, complex projects with interacting files. When seeking help from others it is considered polite to: First, do your best to work through RStudio's debugging tools to diagnose your issue on your own. Often those shiny logs and tracebacks are useful to others trying to help out. Second, strive to minimize the effort required to replicate your issue. You can do this with a reproducible example ("reprex"). Shiny Debugging Errors in Shiny code can be difficult to track down. If you don't know where your problem is coming from, you can track it down with some o…

Okay, edited to add reproducible example, thanks for the info

So if anyone has the same issue, apparently if I use rsconnect::deployApp on a .Rmd file it will not fill the pane, but when I upload separate ui.R and server.R files it works as intended.
