phase_banner: Phase banner

In shinyGovstyle: Custom Gov Style Inputs for Shiny

Phase banner

Description

This function creates the GOV.UK phase banner component, used to show that a service is still being worked on, for example in alpha or beta.

Usage

phase_banner(
  inputId,
  type,
  label = NULL,
  feedback_url = NULL,
  width = "standard"
)

Arguments

inputId	The id assigned to the component's root element. For Shiny input components this is also the name used to access the value via ⁠input$<inputId>⁠.
type	Main type of label e.g. alpha or beta. Can be any word
label	Text to display. Accepts a plain character string, or shiny tag objects such as shiny::tags$b("Bold") or a shiny::tagList(). Not required if feedback_url is supplied instead.
feedback_url	Optional URL used to auto-generate the standard GOV.UK phase banner feedback text, e.g. "This is a new service - your feedback (opens in new tab) will help us to improve it.", with feedback linking to feedback_url. If feedback_url starts with ⁠mailto:⁠ the text instead reads "This is a new service - please contact [email address] if you have any questions or feedback.". Exactly one of label or feedback_url must be supplied.
width	Width of the component. One of "standard" (the default, GOV.UK's usual 960px content width), "three-quarters" (three-quarters of the viewport, never narrower than standard), "full" (no max-width, so the container fills the viewport, with grid gutters also removed), or a CSS length (e.g. "1400px", "90vw") for a custom max-width.

Value

a phase banner HTML shiny tag object
