I have an agreement form I use a lot where I want the signer to choose one of two checkboxes, "yes, I agree to [a sub agreement]" vs "no, I do not agree to [the sub agreement]." I want it to be required that the signer check one of the boxes. Obviously, I can't make each of the two boxes required, because then the signer would be giving contradictory answers to the question.

More generally, my feature request is that it be possible to have more complex field requirements. One version would require that only one out of a group of fields be filled. Another version would require that at least one out of a group of fields be filled.

I realize that in some circumstances, I could limit a signer to choosing one out of several options by using a droplist of answers, and making that field required. However, in my situation, I have reasons to prefer offering the question with two separate check box answers, "yes" vs "no." And regardless, the droplist option does not solve the problem when I want to allow multiple answers requiring at least one with it being optional to give additional answers.

This is related to, but different, from another feature request, "Conditional Required Fields," https://acrobat.uservoice.com/forums/590923-acrobat-for-windows-and-mac/suggestions/44924401-conditional-required-fields.

Thanks!
