Is it possible to restrict the values that can be entered in a text field input

Hi there

I'm trying to create a questionnaire tool where learners have to rate a selection of statements in order of their preference (1-4).

Is it possible to only allow an input from a text field to be limited to 1,2,3, or 4?

Also, is it possible to only allow each value to be entered once?

Many thanks in advance.

David
