Issue with fixedPanel responsive = FALSE argument about shiny HOT 3 CLOSED

Unfortunately those docs are just very outdated. The responsive argument was marked as deprecated in 2014 (when shiny upgraded from Bootstrap 2 to Bootstrap 3) and then fully removed from fluidPage() and fixedPage() in shiny 1.7.0 (released 3 years ago).

I think the article date on that page isn't quite telling the truth, which leads to additional confusion. I'll make sure we have an internal ticket to update that article.

Given that this isn't an option anymore. Do you have any suggestions on another way to turn off the responsive bootstrap features for a shiny app?

This argument however doesn't work to turn off responsive bootstrap features. When the window in the example shiny app code above becomes smaller than 768px the wellPanel() is resized stacking the widgets.

FWIW, responsive = FALSE was about turning off the responsive page width (i.e., the container that adds margins to the page), not about preventing the collapse of grid layout on small devices (I don't think we've ever supported that). Today, if you wanted that same responsive = FALSE, you'd use bootstrapPage(), not fixedPage()/fluidPage().

Thankfully, it seems like a new Bootstrap stacking feature might be exactly what you're looking for. We don't have an official wrapper for it, but you could write the HTML:

library(shiny)
library(bslib)

ui <- page_fixed(
  titlePanel("Old Faithful Geyser Data"),
  div(
    class = "hstack p-3 gap-3 justify-content-center bg-light border rounded",
    sliderInput(
      "a", "slider 1",
      min = 1,
      max = 10,
      value = 3
    ),
    sliderInput(
      "b", "slider 2",
      min = 1,
      max = 10,
      value = 5
    ),
    checkboxGroupInput(
      "c", "checkbox 1",
      choices = c("a", "b", "c", "d"),
      selected = "a"
    ) 
  )
)

shinyApp(ui, function(input, output) {})
