How do I make Checkbox questions required?

Question?

I have a checkbox question in my survey. I can't seem to find the option to make it required. Am I missing something?

Support Response:

Hi

Checkbox items do not have the standard required field that other question types do since you can choose more than one option in a checkbox question. Instead, to make it required, you should enter a value of at least 1 in the 'Min to Select' box on the Behavior tab.

Let us know if you have any more questions.

Best,
