How to add bullet points in R Shiny's renderText?

Question

I'm using renderText to display some dynamic output in my Shiny web app. Now how can I include a bullet points in the dynamic output?

Answer 1

Assuming you are using UI.R and not a custom HTML UI, you should be able to use either the HTML function or the tags function for this.

Please be advised I am writing this out of my head, so the code is untested.

HTML("<ul><li>...text...</li><li>...more text...</li></ul>")

Or

tags$div(
  tags$ul(
     tags$li("text")
  )
)

Update: I first missed the dynamic word in your question, which is why I only mentioned UI.R (thanks to @StephaneLaurent for pointing it out).

In order to make your bulleted list dynamic you should use renderUI in your server.R. This function expects the expression it wraps to be HTML. Then, you can specify in your UI.R where to put the list by using uiOutput.

The code would look more or less like this:

UI.R

#other elements before the list
uiOutput("myList")
#other elements after the list

server.R

output$myList <- renderUI(HTML("<ul><li>...text...</li><li>...more text...</li></ul>"))

You can find more information on renderUI in the docs, and a brief explanation about using it for dynamic UIs in the tutorial.
