In one of my contact forms I have a field for telephone number and a field for email address. I don't want to force my visitors to enter both fields, but I would like at least one of them entered before the form can be submitted.
Is there a way of making 'at least one' of a group of fields mandatory?
Thanks.
There is no built in way to make one or the other required. A field is either required, or it is not required.
You can, however, write your own custom validation using the gform_validation hook. So you could do this as a customization. Documentation for the gform_validation hook can be found here:

Thanks for the quick reply Carl. As a work-around, I was able to use a multiple-choice field with two options, both of which conditionally show a new field. Making that multiple-choice field required, technically makes either of the two conditional fields below it required.
Not the most ideal solution, but in an either or instance, it does the trick.
I, like many others, still vote for the ability to group fields (beyond sections), and apply conditional requirement logic to the fields in groups :)
