if (interactive()) {

library(shiny)
library(shinyWidgets)


data("mpg", package = "ggplot2")


ui <- fluidPage(
  fluidRow(
    column(
      width = 10, offset = 1,
      tags$h3("Filter data with picker group"),
      panel(
        pickerGroupUI(
          id = "my-filters",
          params = list(
            manufacturer = list(inputId = "manufacturer", label = "Manufacturer:"),
            model = list(inputId = "model", label = "Model:"),
            trans = list(inputId = "trans", label = "Trans:"),
            class = list(inputId = "class", label = "Class:")
          )
        ), status = "primary"
      ),
      DT::dataTableOutput(outputId = "table")
    )
  )

    id = "my-filters",
    data = mpg,
    vars = c("manufacturer", "model", "trans", "class")
  )
  output$table <- DT::renderDataTable(res_mod())
