Focus manages element focus in forms. By default first visible and enabled input element(e.g. text, textarea, select) is chosen to receive focus automatically. It is also possible to explicitly declare the component to receive focus via the for attribute.
Focus is also aware of failed validations, first invalid input component receives a focus automatically.
