QUESTION

How have a image in the center of the dashboard header in Shinydashboard R?

Asked 2022-Jan-13 at 21:58

I have the following code that makes a simple shiny app.

```
library(shinydashboard)
library(shiny)
ui <- dashboardPage(
  dashboardHeader(title = tags$img(src='https://cdn.vox-cdn.com/thumbor/Ous3VQj1sn4tvb3H13rIu8eGoZs=/0x0:2012x1341/1400x788/filters:focal(0x0:2012x1341):format(jpeg)/cdn.vox-cdn.com/uploads/chorus_image/image/47070706/google2.0.0.jpg', height = '60', width ='100')),
  dashboardSidebar(
    sidebarMenuOutput("menu")
  ),
  dashboardBody()
)

server <- function(input, output) {
  output$menu <- renderMenu({
    sidebarMenu(
      menuItem("Overview", icon = icon("tachometer"))
      
    )
  })
}
shinyApp(ui, server)
```

And the image is outputted on top of the menu to the right, but my goal would be to have the image be more in the middle of the dashboard. I know the menu shifts the navabr a bit but I would like to keep it as center as possible.

enter image description here

But my desired output would be like this. I made a sample with paint. Is it possible to still have some text or if a reference can be posted where I can learn more about the dashboard header function I would appreciate it.

Here you go

There is no way you can add the image to the header part on the right side with the function from shinydashboard, but let's have fun with the latest htmltools by injecting styles and tags into the header.

library(shinydashboard)
library(shiny)
header_img <- tags$img(
    src='https://cdn.vox-cdn.com/thumbor/Ous3VQj1sn4tvb3H13rIu8eGoZs=/0x0:2012x1341/1400x788/filters:focal(0x0:2012x1341):format(jpeg)/cdn.vox-cdn.com/uploads/chorus_image/image/47070706/google2.0.0.jpg',
    style = 'height: 50px; width: 100px; position: absolute; left: 50%; transform: translateX(-50%);'
)
header <-  htmltools::tagQuery(dashboardHeader(title = ""))
header <- header$
    addAttrs(style = "position: relative")$ # add some styles to the header 
    find(".navbar.navbar-static-top")$ # find the header right side
    append(header_img)$ # inject our img
    allTags()

ui <- dashboardPage(
    header,
    dashboardSidebar(
        sidebarMenuOutput("menu")
    ),
    dashboardBody()
)

server <- function(input, output) {
    output$menu <- renderMenu({
        sidebarMenu(
            menuItem("Overview", icon = icon("tachometer"))
            
        )
    })
}
shinyApp(ui, server)

The img is placed on the center of right side header, not the center of the entire header length. If you want to adjust to the center of the whole length, try to change translateX(-50%) of the img to a number you like.
