I'm trying to create a fillable PDF form that allows a user to click a button to add new fields. Basically, I want the user to be able to add a new set of fields to record details of a new person.

So if the default form has one 'person' set of fields (name, DOB, address), I want there to be an option to 'add another person', and fill out the same fields. The new fields would have to have a different value to the previous fields (e.g. name1, name2 etc).

Is this possible? How is it done?
