Create a textarea input control

textAreaInput(inputId, label, value = "", width = NULL, height = NULL,
  cols = NULL, rows = NULL, placeholder = NULL, resize = NULL)


inputId The input slot that will be used to access the value.
label Display label for the control, or NULL for no label.
value Initial value.
width The width of the input, e.g. '400px', or '100%'; see validateCssUnit.
height The height of the input, e.g. '400px', or '100%'; see validateCssUnit.
cols Value of the visible character columns of the input, e.g. 80. If used with width, width will take precedence in the browser's rendering.
rows The value of the visible character rows of the input, e.g. 6. If used with height, height will take precedence in the browser's rendering.
placeholder A character string giving the user a hint as to what can be entered into the control. Internet Explorer 8 and 9 do not support this option.
resize Which directions the textarea box can be resized. Can be one of "both", "none", "vertical", and "horizontal". The default, NULL, will use the client browser's default setting for resizing textareas.


A textarea input control that can be added to a UI definition.


Create a textarea input control for entry of unstructured text values.


## Only run examples in interactive R sessions if (interactive()) { ui <- fluidPage( textAreaInput("caption", "Caption", "Data Summary", width = "1000px"), verbatimTextOutput("value") ) server <- function(input, output) { output$value <- renderText({ input$caption }) } shinyApp(ui, server) }
