Creating fields in a form

[Anonymous]

Is it possible to add non-Marketo fields in a form?  For example, creating a form to register for an event and want to add a field to select the correct event on a roadshow.  Is this possible?

You can definitely do this.
You will need a custom Marketo only field. See this walkthrough:
