There are two document options when using grouped checkboxes with the API.
When using Hellosign templates, you can group checkboxes directly in the template editor. The links below show the hellosign.com editor, however, the process is the same when using the embedded iFrame editor.
When sending documents out to sign, grouped checkboxes can be used with text tags.
Checkbox field grouping
Checkbox field groups accept an optional validation rule, which must be met before the user can submit the signed document. These are the options you can specify for validation rule.
|require_0-1||Requires at most one checkbox within the group to be checked (radio button functionality)|
|require_1||Requires only one checkbox within the group to be checked|
|require_1-ormore||Requires at least one checkbox within the group to be checked|
NOTE: We do not currently offer the grouping functionality with checkboxes created with form_fields_per_document. If you'd like to be added to that feature request, please write into firstname.lastname@example.org and we can keep you posted.
The workaround is to create and group checkboxes with text tags and use form_fields_per_document for the rest of the fields you'd like to add.
