Validate multiple checkbox group

Question

I have a form, with multiple checkboxes (over 150). I need the user to select at lease one item. I know how to do this one checkbox group.
Because I have too many checkboxes, I decided to group them in different tabs, So I created multiple checkbox groups. Now I need to make sure that user selects at least one checkbox from EITHER groups.
I tried to name the groups the same and make them required, but that causes that user select an item from each group. All I need to do is validate the form so that only one item from either group satisfies the requirement and we can move forward.

Can you please help.
Thanks

Hi omidhz,

You will need to write a Custom validation to check that - or re-design the form - you could probably use a Custom Code action with a table layout to group them in four or five columns in the same checkbox group.

Validate at least one selection across multiple checkbox groups.
