R: Create a textarea input control

textAreaInput {shiny} | R Documentation

## Create a textarea input control

### Description

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

### Usage

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

### Arguments

`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.

### Value

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

    server <- function(input, output) {
      output$value <- renderText({ input$caption })
    }
    shinyApp(ui, server)
