We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Currently, the only way to do that would be to create a separate checkbox field for each choice and set each one to required, instead of having multiple choices in one field. (CSS could always be injected to make the checkboxes look like they belong to a single field.)
If you would like additional assistance with this, please let us know.
