Variables for {shinydashboard}

Colors

There’s a fixed list of colors that you can use in valueBox, infoBox, box, but which are also used for other components like the header. Some colors are associated with a status, for example in valueBox you can use color = "light-blue", but in box you have to use status = "pimary" for the same color. The function adminlte_color() allow you to define those colors:

With the following code we are gonna change the light-blue color that is also the color for the primary status and for the header:

adminlte_color(
  light_blue = "#086A87"
)

With classic colors from {shinydashboard}, it look like:

With our new theme, we have changed the color of four elements:

Here, we have modified only one color, but you can set values for all the other ones.

Sidebar

One of the main features of {shinydashboard} is the side menu, which can be modified with adminlte_sidebar().

In the example below, we change the default width of the sidebar as well as its color:

adminlte_sidebar(
  width = "400px",
  dark_bg = "#D8DEE9",
  dark_hover_bg = "#81A1C1",
  dark_color = "#2E3440"
)

With our new theme:

adminlte_global(
  content_bg = "#FFFFFF",
  box_bg = "#D8DEE9", 
  info_box_bg = "#D8DEE9"
)

Full application

Here’s the code to create the theme and use it in a dashboard application:

library(fresh)
# Create the theme
mytheme <- create_theme(
  adminlte_color(
    light_blue = "#434C5E"
  ),
  adminlte_sidebar(
    width = "400px",
    dark_bg = "#D8DEE9",
    dark_hover_bg = "#81A1C1",
    dark_color = "#2E3440"
  ),
  adminlte_global(
    content_bg = "#FFF",
    box_bg = "#D8DEE9", 
    info_box_bg = "#D8DEE9"
  )
)


library(shiny)
library(shinydashboard)

ui <- dashboardPage(
  header = dashboardHeader(title = "My dashboard"),
  sidebar = dashboardSidebar(
    sidebarMenu(
      menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
      menuItem("Settings", tabName = "settings", icon = icon("sliders"))
    )
  ),
  body = dashboardBody(
    
    use_theme(mytheme), # <-- use the theme
    
    tabItems(
      tabItem(
        "dashboard",
        
        # infoBoxes
        fluidRow(
          infoBox(
            "Orders", "123", "Subtitle", icon = icon("credit-card"),

          box(
            title = "A box", solidHeader = TRUE, width = 4,
            status = "primary",
            "Content of the box"
          )
        )
      )
    )
  )
)

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