I'm looking for a way to pre-fill text areas with some brief instructional text. And then I need the text to disappear when the field is clicked on. I've seen a lot of other forms do this, but I don't know how to achieve it in DTRegister. Is this possible? If not... it should be a new feature... would be very helpful.
This is not currently possible. I'd suggest using the "Description" parameter for the field as it will display a tooltip next to the field for giving instructions.
