How to create TextArea as input in a Shiny webapp in R?

Question

I am trying to create simple webapp where I want to take in multiline input from user using HTML textarea control. Is there any out of the box way of creating such an input

Answer 1

You can add a textarea using tags and it should be picked up by Shiny automatically:

tags$textarea(id="foo", rows=3, cols=40, "Default value")

Or if you're more comfortable with straight HTML you can also do

HTML('Default value')

In either case, input$foo should reflect the textarea's value.
