I've added several check boxes which correspond with separate "product interest" fields in the CRM. People submitting the form must select at least one or more boxes. Unfortunately in Marketo each individual field has the ability to be marked as "required" but that would mean in theory every box would need to be ticked, so it won't work.
It would be useful if you could put these checkboxes in a field set and then use "out of the box" vaildation rules to say "required - at least one selection must be made".
I've heard the only way to achieve this would be using Javascript to run the validation rules that aren't supported in the form builder. Does anyone know if there's actually a way to do this within the form builder itself?
Thanks!
