In the code above, we're creating a new FieldList instance and adding three fields to it – an input field for the first name, an input field for the last name, and a textarea field for the message. We're using the create method of each class to create a new instance of the field and passing in the field name and label as arguments. The SilverStripe\Forms namespace indicates that this example uses the SilverStripe framework's Form FieldList.
