Make checkbox question mandatory

[veram34903487]

Hi,

I was wondering if there is a clever way to mark a question containing checkbox questions (more than 1 answer possible) mandatory that at least 1 checkbox is ticked.

In the example: I can define an error message for Container 6 if no checkbox out of those three are ticked. I know I can make each single checkbox mandatory, but that's not the point and would be detrimental in my survey case.

Thanks!

Hi,

Use simple JS to check this, Array's map() and includes() functions should suffice.

Thanks,
