The Checkbox field allows you to add options to your form for your respondents to select from. This field is best used for forms with questions requiring more than one answer, unlike the Radio field which is useful when you want your respondents to select only one answer. The checkbox field is located under the Choice Option section of the Drag & Drop field in the builder page of your form as shown in the image below.
With this field, you can add validation to the checkbox such that your respondent does not select more than the required number of answers you have set. To add validation to your checkbox field:
1. Click on the Edit Icon for the field.this will display a modal to allow for editing of the field.
2. Click on the Validation word at the top of the modal, this will display two input boxes with minimum selections allowed and maximum selection allowed for you to input the minimum and maximum.
3. Click on the Save button at the bottom of the edit modal to save your options.
