If called with no arguments, it will return NULL and set no conditions.

Usage

Examples

if (interactive()) {
  library(surveydown)

  # Use sd_show_if() to conditionally show/hide questions:
  # server <- function(input, output, session) {
  #   sd_show_if(
  #     input$has_car == "yes" ~ "car_make",
  #     input$employed == "yes" ~ "job_title",
  #     input$age >= 18 ~ "adult_questions_page"
  #   )
  #   sd_server()
  # }

  # Find a working directory and start from a template:
  sd_create_survey(template = "conditional_showing")
  # This creates survey.qmd and app.R - launch the survey using app.R
