There is a text field in a form that I would like to auto populate radio options.

Image 3 Text Fields one for first name, middle name and Last name.

There are also 3 radio group options for the person on how their name displayed

First Middle Last
First M. Last
First L.

I would like these three radio option labels to be populated as the user types in the form fields. Is this possible? If so can you point me in the right direction?
