contents_link: Contents link function

In shinyGovstyle: Custom Gov Style Inputs for Shiny

Contents link function

Description

This function creates an action link to nav between tabs and optionally link to subcontents headers.

contents_link() was deprecated in shinyGovstyle 0.2.0 and will be removed in shinyGovstyle 1.0.0. For multi-page layouts, service_navigation() is the recommended approach: it gives users the GOV.UK service navigation bar for moving between pages (tab panels), with service_navigation_server() and navigate_to() to switch panels from the server.

service_navigation() is not a drop-in replacement. It has no equivalent of the subcontents links, and it does not create links to headings within a page. For those, use ordinary links to heading ids, e.g. heading_text("Methodology", id = "methodology") with shiny::tags$a(href = "#methodology", class = "govuk-link", "Methodology").

Usage

contents_link(link_text, input_id, subcontents_text_list, subcontents_id_list)

Arguments

link_text	vector of link text for contents
input_id	contents button Id
subcontents_text_list	vector of link text for subcontents
subcontents_id_list	vector of link Ids for subcontents. If missing automatically matches to Id in heading_text()

Value

an action button HTML shiny tag object

Examples

# Multi-page layout: service_navigation() moves between tab panels
ui <- shinyGovstyle::gov_page(
  shinyGovstyle::header(org_name = "Example", service_name = "My service"),
  shinyGovstyle::service_navigation(
    c("Summary" = "summary", "Methodology" = "methodology")
  ),
  shinyGovstyle::gov_main_layout(
    bslib::navset_hidden(
      id = "pages",
      bslib::nav_panel_hidden(
        "summary",
        shinyGovstyle::heading_text("Summary", size = "l"),
        # In-page anchor links are ordinary links to heading ids
        shiny::tags$a(
          href = "#key-findings",
          class = "govuk-link",
          "Key findings"
        ),
        shinyGovstyle::heading_text(
          "Key findings",
          size = "m",
          level = 2,
          id = "key-findings"
        )
      ),
      bslib::nav_panel_hidden(
        "methodology",
        shinyGovstyle::heading_text("Methodology", size = "l")
      )
    )
  ),
  shinyGovstyle::footer(full = TRUE)
