Hello! I have custom field in submitting page of the gamejam. If this field is “single choice” - its all ok. But if it is “multiple choices” and have ‘required’ checked - user need to check every checkbox. Bug?

I mean, is the supposed behaviour - the whole field is required, not the every choice in multiple choices? If i want my users to always check at least one choice, but have opportunitie check, for example, 2 checkboxes of 10? Is there a way to do it for now, or it was a bug?)
