For the last part of this chapter, we will go a bit further with the customization of forms.

A part of our meetups website requires a user to enter their house address so that they can receive a membership card that will be directly sent out to them. Since we already have a relatively good idea where that user is coming from, we will preset the country for them in the form. Here, we only differentiate between users coming from within or outside the USA to decide if they must fill in the state they are coming from.
