TextArea represents a multi-line plain-text editing control, useful when you want to allow users to enter a sizeable amount of free-form text, for example a comment on a review or feedback form.
When to use
Make sure the default size of the TextArea covers the requested amount of text.
A user needs to input unique information that cannot be predicted with a
preset of options.
A user needs to input memorable data that can be entered
more quickly in a free-hand format versus a more complex control.
When not to use
A user needs to input a short amount of text. Use a
TextInput instead. - If a user can only enter an
option from a predefined list then avoid using a free-form text input as it is
likely to result in an error. Consider using a selection control such as a
dropdown, select, or radio button group instead.
