Text Area Component

See at USWDS

The Text Area Component is designed for a text area field in a form backed by an ActiveModel object. In the preview example that is the body attribute of an Article object.

The preview allows you to set error messages on the title attribute. But the component displays the full message of the errors. That is why the attribute name is prepended.
