I need to make a checkbox in Word 2011 Mac that is dependent on another checkbox. I need the user to check either the YES box OR the NO box, and not be able to check both boxes. Does anyone know how to do this?
Generally, you would choose a Radio button for that type of function.
A checkbox has a certain expected function. A radio button has what you're looking for. Forcing a checkbox to act like a radio button is confusing to the user.
If a junior developer came to me wanting to do that, I'd tell him "No. Use the proper widget."
