Is it possible to use validateF7Input() on an input rendered on the server using renderUI() ? about shinymobile HOT 2 OPEN

Update on this, I got it working well enough by using an if statement at the start of my observe block, but I could still use some help if anyone has suggestions. Since input$conditional_input1,2and3 only exists if user answers 'Yes' to a previous input, the following works pretty well, but I'm sure there is a more elegant way to achieve this:

    observe({
      # Thought that req() would work but ended up working better with subsequent if statement
      # req(input$conditional_input1)
      if (!isTruthy(input$conditional_input1) && !isTruthy(input$conditional_input2) && !isTruthy(input$conditional_input3)) {
      print('conditionally running')
      lapply(c("conditional_input1", "conditional_input2", "conditional_input3", function(n) {
        observe({
          validateF7Input(
            inputId = ns(n),
            pattern = "^\\d*\\.?\\d+$", # regex for int or float
            error = "Please enter a number"
          )
        })
      }
      )
      }
    })

Apologies that this example or the examples above aren't given in a demo shiny app.

Thx for your consideration. FYI for my use case I ended up going with your radio input combined with shinyjs show() and hide() and that seems to be working well so far. I decided the falsy check above and the observe() within observe() was too hard to reason about and the input warnings weren't working perfectly.
