Problem with Minimum Length and Maximum Length in Checkbox Group was created by Oleg
Hi,
don't work "Minimum Length" and "Maximum Length" options in Checkbox Group. I set both options to "1", but user can check both checkboxes in group simultaneously; see attachments.
Can I solve this problem?

the verification only takes place after the submit button has been pressed.

Wrong selection before submitting the form:

Hello Oleg,

instead of min=1 and max=1 it would be better to set "Required" and max=1.
