is there a way to use shinyvalidate with a variable number of inputs?

Hello. I'm a bit new to shiny validate, but it seems really great. My code asks the user to first state how many treatments there are (input$in1) and then displays that many textInput fields for the names of the treatments (using a string name for the input ids)

Is there a way to validate these fields as the user enters the names? My attempt at a reprex is below.

if (interactive()) {
  
  library(shiny)
  library(shinyjs)
  library(shinyvalidate)
  ui <- fluidPage(
    numericInput('in1', 'Enter the number of treatments between 2 and 6', value = 2),
    shinyjs::hidden(div(id = "treatmentNamesID",
      uiOutput("treatmentNamesInput")
      )),
      verbatimTextOutput("theTreatmentNames")
    )
  server <- function(input, output) {
    iv_in1 <- InputValidator$new()
    iv_in1$add_rule("in1", sv_required())
    iv_in1$add_rule("in1", ~ if (!((input$in1 >= 2 ) && (input$in1 <= 6))) "Not between two and  6")
    iv_in1$add_rule("in1", ~ if (!is.integer(input$in1)) "Not an integer")
    iv_in1$enable()
    observeEvent(input$in1,{
      shinyjs::showElement(id = "treatmentNamesID")
    })
    observeEvent(input$printButton, {
      req(iv_in1$is_valid())
      TrtNames = c()
      for (i in 1:input$in1) {
        fname = paste0("TrtNames", i)
        TrtNames = c(TrtNames,input[[fname]])
      }
      output$theTreatmentNames = renderPrint({
        print(TrtNames)
      })
  })
    output$treatmentNamesInput <- renderUI({
      req(iv_in1$is_valid())
      div(id = "treatmentNamesID",
          hr(),
          fluidRow(
            column(2, h4("Enter treatment names"))
          ),
          fluidRow(
            lapply(1:input$in1, function(i) {
              fname = paste0("TrtNames", i)
              column(1,
                     textInput(fname, label = NULL, value = paste0("T", as.character(i))
                     )
              )
            })
          ),
          actionButton("printButton",label = "Press to print treatment names"),
          br()
      )
    })
  }
  
  shinyApp(ui, server)
  
}

my guess would be that you should probably bundle the validation with the control via use of shiny modules

Thanks, nirgrahamuk. I'll be a beginner with shiny modules, but will look into that.
