textAreaInput: 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
)

Value

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

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. This argument will only take effect if there is not a CSS width rule defined for this element; such a rule could come from the width argument of this function or from a containing page layout such as fluidPage().

rows

The value of the visible character rows of the input, e.g. 6. If the height argument is specified, 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.

Server value

A character string of the text input. The default value is "" unless value is provided.
