Set a column as exclusive

When a participant selects an exclusive column in a Multiple Choice Grid question, they cannot select any other columns for that answer.

Exclusive column example

You have created a Multiple Choice Grid question that asks participants to evaluate a variety of department stores based on different criteria. You create a column that says "Never shopped there" and you don't want participants to be able to select both "Never shopped there" and a criterion.

Click Options, and select Make column exclusive choice.
The column is set as exclusive. Any participant who selects an answer from within this column will not be able to select another answer.
