The Textarea is an expandable, multi-row box used for text input. It looks and functions very similarly to a textfield for capturing character input, but it does not have many of the mathematical and java properties associated with it. It is used strictly for capturing text input, and usually that of a longer, free-flow nature, like notes or commentary.
For basic text input of a 100 characters or less, it is better to use the textfield.
Max Length: Perhaps the most important property to use with a textarea the max length property imposes a character limitation on the user input.
