Hello, I have a little problem when I select several check boxes and I want to set a validation rule, in fact the validation option disappears. Validation option only appears when a single box is selected, which is of no use. I am attaching a screenshot of what happens when you select multiple check boxes.
check box + Validation

Hello
Thank you for reaching out here in the DocuSign Community. We appreciate your question and assure you that we are fully committed to providing you with the best service possible.
The checkbox field can be added to your document as a single box or a group of multiple boxes. A checkbox group can include a validation rule to enforce how many checkboxes in the group your signer must select.
Note: Previously, a checkbox was a single element only. Checkbox groups are a newer feature. If you have an existing template with a single checkbox field, it will remain as is the newer properties and options described in this guide will not apply.

Here's an example showing how to add a checkbox group with validation. Click the video for a larger view.
