shinyGovstyle

Apply Gov styled components and formats in shiny

Overview

This package provides some custom widgets to style your app like gov.uk. There are a variety of widgets available, including select, radio, checkboxes as well as styling for headers and footers.

To view details of gov.uk components please visit https://design-system.service.gov.uk/. Most components from https://design-system.service.gov.uk/components/ are available to use through this package.

Installation :

install.packages("shinyGovstyle")

This is also available on conda

conda install r-shinygovstyle

If you want to make use of the development then

remotes::install_github("moj-analytical-services/shinyGovstyle")

To use error and word count elements you will need to load useShinyjs from shinyjs in the UI:

  shinyjs::useShinyjs()

Example Version

Gov style layout

Create a gov style look to the page with a header, footer, font and layout:

ui <- fluidPage(
  #font(),
  shinyGovstyle::header("Justice", "Prototype", logo="shinyGovstyle/images/moj_logo.png"),
  gov_layout(size = "full",
        tags$br(),
        tags$br(),
        tags$br(),
        tags$br(),
        tags$br()
      ),
  footer(TRUE)
)

server <- function(input, output, session) {}

Note: You can only use gov.uk font on service.gov.uk (see https://design-system.service.gov.uk/styles/typography/)

Banner

Add a banner to the header to state in beta or alpha :

ui <- fluidPage(
  shinyGovstyle::header("Justice", "Prototype", logo="shinyGovstyle/images/moj_logo.png"),
  banner("banner", "beta", 'This is a new service – your <a class="govuk-link" href="#">feedback</a> will help us to improve it.'),
  gov_layout(size = "full",
        tags$br(),
        tags$br(),
        tags$br(),
        tags$br(),
        tags$br()
      ),
  footer(TRUE)
)

server <- function(input, output, session) {}

Radio button

Create a gov style radio button :

radio_button_Input(inputId = "name_changed", label = "Have you changed your name?",
                   choices = c("Yes", "No"), inline = TRUE,
                   hint_label = "This includes changing your last name or spelling your name differently.")

Checkbox

Turn checkboxes into gov style ones :

checkbox_Input(
  inputId = "checkID", 
  cb_labels = c("Waste from animal carcasses", "Waste from mines or quarries", "Farm or agricultural waste"),
  checkboxIds = c("op1", "op2", "op3"),
  label = "Which types of waste do you transport?",
  hint_label = "Select all that apply.")

Note that you currently access the values separately through the inputIds you supply or all values through the main inputID.

Button

Gov style button with different styles :

shinyGovstyle::button_Input(inputId = "btn1", label = "default"),
shinyGovstyle::button_Input(inputId = "btn1", label = "start", type = "start"),
shinyGovstyle::button_Input(inputId = "btn1", label = "secondary", type = "secondary"),
shinyGovstyle::button_Input(inputId = "btn1", label = "warning", type = "warning")

Select

Gov style drop down select :

shinyGovstyle::select_Input(
  inputId = "sorter", 
  label = "Sort by",
  select_text = c("Recently published", "Recently updated", "Most views", "Most comments"),
  select_value = c("published", "updated", "view", "comments"))

Date

Gov style date input :

date_Input(
  inputId = "date1",
  label = "What is your date of birth?",
  hint_label = "For example, 31 3 1980")

Note that you currently access the individual values by adding an affix of _day, _month and _year or the full date in dd/mm/yy by using the inputID.

File input

Gov style file input component :

file_Input(inputId = "file1", label = "Upload a file")

Text input

Gov style text input component :

text_Input(inputId = "txt1", label = "Event name")

Text area input

Gov style text area input component :

text_area_Input(
  inputId = "text_area",
  label = "Can you provide more detail?",
  hint_label = "Do not include personal or financial information, like your National Insurance number or credit card details.")

You can also add a word count to the options, which requires an additional argument in the server :

ui <- fluidPage(
  shinyjs::useShinyjs(),
  shinyGovstyle::header("Justice", "", logo="shinyGovstyle/images/moj_logo.png"),
  gov_layout(size = "full",
        text_area_Input(
          inputId = "text_area",
          label = "Can you provide more detail?",
          hint_label =  "Do not include personal or financial information, like 
                         your National Insurance number or credit card details.",
          word_limit = 300)
  ),
  footer(TRUE)
)

# Define server logic required to draw a histogram
server <- function(input, output, session) {
  observeEvent(input$text_area,
    word_count(inputId = "text_area", input = input$text_area, word_limit = 300)
  )
}

Warning

Gov style warning component :

warning_text(inputId = "warn", text = "You can be fined up to £5,000 if you do not register.")

Insert text

Gov style insert text component :

insert_text(inputId = "insertId",
            text = "It can take up to 8 weeks to register a lasting power of attorney 
                    if there are no mistakes in the application.")

Details

Gov style details component :

 details(
  inputId = "detID",
  label = "Help with nationality",
  help_text = "We need to know your nationality so we can work out which elections you’re 
              entitled to vote in. If you cannot provide your nationality, you’ll have to 
              send copies of identity documents through the post.")

Panel

Gov style panel component :

panel_output(
  inputId = "panId", 
  main_text = "Application complete", 
  sub_text = "Your reference number <br> <strong>HDJ2123F</strong>")

noti_banner(
  "notId",
  title_txt = "Important",
  body_txt = Example text,
  type = "standard"
)

        "How people read"
       ),
      c("This is the content for Writing well for the web.",
        "This is the content for Writing well for specialists.",
        "This is the content for Know your audience.",
        "This is the content for How people read."
       ))

Table

Gov style table component :

Months <- c("January", "February", "March")
Bikes <- c("£85", "£75", "£165")
Cars <- c("£95", "£55", "£125")
example_data <- data.frame(Months, Bikes, Cars)

shinyGovstyle::govTable(
      "tab1", example_data, "Test", "l", num_col = c(2,3),
      width_overwrite = c("one-half", "one-quarter", "one-quarter"))

Tabs

  # Create an example dataset
  tabs <- c(rep("Past Day", 3),
            rep("Past Week", 3),
            rep("Past Month", 3),
            rep("Past Year", 3))
  Case_manager <- rep(c("David Francis", "Paul Farmer", "Rita Patel"),4)
  Cases_open <- c(3, 1, 2, 24, 16, 24, 98, 122, 126, 1380, 1129, 1539)
  Cases_closed <- c(0, 0, 0, 18, 20, 27, 95, 131, 142, 1472, 1083, 1265)
  data <- data.frame(tabs, Case_manager, Cases_open, Cases_closed)

  ui <- fluidPage(
    shinyGovstyle::header(
      main_text = "Example",
      secondary_text = "User Examples",
      logo="shinyGovstyle/images/moj_logo.png"),

  )

  server <- function(input, output, session) {}
  shinyApp(ui = ui, server = server)

  observeEvent(input$cookieAccept, {
    shinyjs::show(id = "cookieAcceptDiv")
    shinyjs::hide(id = "cookieMain")
  })

  observeEvent(input$cookieReject, {
    shinyjs::show(id = "cookieRejectDiv")

    #Need to link here to where further info is located.  You can
    #updateTabsetPanel to have a cookie page for instance
  })

}
shinyApp(ui = ui, server = server)

Error

Add errors to components when not filled in correctly. Most components have an option to add :

ui <- fluidPage(
  shinyjs::useShinyjs(),
  shinyGovstyle::header("Justice", "", logo="shinyGovstyle/images/moj_logo.png"),
  gov_layout(size = "full",
        text_area_Input(
          "text_area",
          "Can you provide more detail?",
          "Do not include personal or financial information, like your National Insurance number or credit card details.",
          word_limit = 300, error = TRUE, error_message = "Error"),

        button_Input("btn1", "Toggle error")
  ),
  footer(TRUE)
)

server <- function(input, output, session) {
  err <<- FALSE
  observeEvent(input$btn1,{
    if (err) {
      err <<- FALSE
      error_off("text_area")
    }
    else {
      err <<- TRUE
      error_on("text_area", "You have an error")
    }
  }
  )
}
