We've had requests from our business partners to have groups of checkboxes where the user needs to select at least one option. (A "please select all which apply" situation).

We can't have each checkbox itself be required because not all apply to each user. Radio buttons don't work because some users will need to select multiple options.

Being able to create a checkbox group with an overall "at least one" requirement would be great. Right now the only option is to use custom JavaScript to validate it.

Thanks.
