A "select answer" question

I have a form with fields with dropdownlists, radiobuttons, etc etc

In many of the fields I have a "I dont know" alternative or "I cant answer" alternative that the user can choose.

But instead to have this answer printed out on the profile like this example:

1.What did you do yesterday? - I dont know
2.What did you do last week? - I dont know
3.What did you do last month? - Was in a store

I want too hide the "I dont know" fields on the profile view. Like I can do with a empty text field.

And I mean hide the WHOLE field. both the question and the answer.

You'll probably need to use CB Conditionals and condition the field against it self (only do this for profile view, it will behave oddly anywhere else). You can also try using the Profile Value Layout with the below IF substitution usage to see if that'll work.
