CRAN status R-CMD-check

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()

Components available :

Gov style layout

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

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

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) {}

Create contents and subcontents links to sidebar to navigate page.

Important: contents_link() requires the following UI structure to enable the js to work as it relies on the IDs for each section to then point a users focus to. This can also be found in run_example():

shiny::fluidpage(
  shinygovstyle::header(
    main_text = "example",
    secondary_text = "user examples",
    logo = "shinygovstyle/images/moj_logo.png"
  ),
  gov_row(
    shiny::column(
      width = 3,
      id = "nav", # DO NOT REMOVE ID
      shiny::tags$div(
        id = "govuk-contents-box", # DO NOT REMOVE ID 
       class = "govuk-contents-box",  # DO NOT REMOVE CLASS
        shiny::tags$h2("contents"), 
        
        # CONTENTS LINKS GO HERE
        )
      ),
      shiny::column(
        width = 9,
        id = "main-col", # DO NOT REMOVE ID
        shiny::tabsetpanel(
        type = "hidden",
        id = "tab-container", # DO NOT REMOVE ID 
                           
        # TAB PANELS GO HERE 
        )
      )
  )
)

You can create a content links without subcontents links:

contents_link(
  link_text = "Cookies",
  input_id = "cookies_button")

Or with subcontents links:

contents_link(
  link_text = "Feedback types",
  input_id = "feedback_types_button",
  subcontents_text_list =  c("tag_Input", "details"))

If you use subcontents_text_list without specifying subcontents_id_list then the subcontents links will automatically link to shinyGovstyle::heading_text() elements where the header label matches the subcontents_text_list label.

Use subcontents_id_list to link a subcontents link to a shinyGovstyle::heading_text() with a custom id argument. The order needs to match that of subcontents_text_list.

Add as a NA to your vector any subcontents links where you still want to use the automatic link id for.

contents_link(
  link_text = "Tables, tabs and accordions",
  input_id = "tables_tabs_and_accordions_button",
  subcontents_text_list = c("govTable", "govTabs", "button_Input"),
  subcontents_id_list = c(NA, NA, "button_input_tables_tabs_accordions")
)

Contents links will need a shiny::observeEvent() in the server to switch between tabset panels.

ui <- shiny::fluidPage(
  shinyGovstyle::header(
    main_text = "Example",
    secondary_text = "User Examples",
    logo = "shinyGovstyle/images/moj_logo.png"
  ),
  gov_row(
    shiny::column(
      width = 3,
      id = "nav", # DO NOT REMOVE ID 
      
      shiny::tags$div( # DO NOT REMOVE DIV
        shiny::tags$h2("Contents"),
        contents_link(
          "Tables, tabs and accordions",
          "tables_tabs_and_accordions_button",
        ),
        contents_link("Feedback types", "feedback_types_button"),
      )
    ),
    shiny::column(
      width = 9,
      id = "main_col", # DO NOT REMOVE ID 
      shiny::tabsetPanel(
        type = "hidden",
        id = "tab-container", # DO NOT REMOVE ID 
        
        shiny::tabPanel(
          "Tables, tabs and accordions",
          value = "tables_tabs_and_accordions",
          gov_layout(size = "Tables, tabs and accordions", 
                     heading_text("Tables, tabs and accordions", size = "l"))
        ),
        
        shiny::tabPanel(
          "Feedback Types",
          value = "feedback_types",
          gov_layout(size = "two-thirds", 
                     heading_text("Feedback types", size = "l"))
        ),
      )
      
    )
  )
)

server <- function(input, output, session) {
  shiny::observeEvent(input$tables_tabs_and_accordions_button, {
    shiny::updateTabsetPanel(session, "tab-container", selected = "tables_tabs_and_accordions")
  })
  
  shiny::observeEvent(input$feedback_types_button, {
    shiny::updateTabsetPanel(session, "tab-container", selected = "feedback_types")
  })
  
}
shiny::shinyApp(ui = ui, server = server)
}

Subcontents links work automatically and do not need to a shiny::observeEvent() in the server.

Heading text

Use heading text to create headings.

You can adjust the text size by setting size to ‘xl’, ‘l’, ‘m’, or ‘s’. size defaults to ‘xl’.

heading_text(text_input = "I am the default extra large text", size = "xl"),
heading_text(text_input = "I am large text", size = "l"),
heading_text(text_input = "I am medium text", size = "m"),
heading_text(text_input = "I am small text", size = "s")

You can use id to create a custom id to link with subcontents_id_list from shinyGovstyle::contents_link. This can be helpful when you have identically named headings.

heading_text(text_input = "I am the default extra large text", id = "custom_id")

Radio button

Create a gov style radio button :
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

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 : button

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 : 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

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

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

Text input

Gov style text input component : text_input

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

Text area input

Gov style text area input component : text_area

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 : text_area

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 : text_area

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 : text_area

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

 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.")

      "acc1",
      c("Writing well for the web",
        "Writing well for specialists",
        "Know your audience",
        "How people read"
       ),
      c("This is the content for Writing well for the web.",
        "This is the content for Writing well for specialists.",
