Can I specify a minimum number of choices for a multiple choice field?

Yes, you can specify a minimum number of choices for a Multiple choice field.

Once you have added a Multiple choice field, in the right side panel, under the Validation section, you will find the Min. no of choices option.

Min/Max choices

Use cases

If you want your respondents to select a specific number of choices (e.g. exactly 2 choices), you’ll need to specify the same value for both the maximum and the minimum number of choices. Make sure the value typed in for the Min no. of choices doesn’t exceed the value you have for your Max no. of choices, otherwise, you’ll receive an error.


When your respondents don’t select the minimum number of choices you’ve set up, they will receive an error message. You can change the text of the message in the Languages → System Messages section.

  2. I have a form for which I would like members to select one of three choices. I limited the number to 1, but if someone selects, say choice, 1 then tries to select choice 2 they receive an error message (you have reached the max no to select). They must ‘unmark’ their choice then select a new choice. My Question is: how can I allow them to pick any one selection, then click on another selection canceling the first choice. Also, as I put the first choice as the default, can they pass this item completely and have the form default to selection one?

    1. Hello John!

      If you want your members to select only a single choice, we’d recommend you use radio buttons instead of checkboxes. Radio buttons allow a single selection and automatically deselects the option when another one is selected. You’ll find the Radio buttons field in the Basic Fields panel of your form editor. Read more about the Radio buttons field here.
