+By default all inputs are required. When the form object includes `ActiveModel::Validations`
 (which, for example, happens with Active Record models), fields are required only when there is `presence` validation.
 Otherwise, **Simple Form** will mark fields as optional. For performance reasons, this
 detection is skipped on validations that make use of conditional options, such as `:if` and `:unless`.
