Mandatory for ranking means that all items must be ranked. Turn off mandatory and you'll get between 1 and 3 answers, as desired.
Yes I had got that but I wonder if Mandatory *should* mean that you have to rank all or just meet the minimum. I have 4 choices, 3 locations and one 'no preferance'. I need to be sure the person taking the survey makes a positive decision (hence mandatory) but I also want to allow for the person having no preferance (which perversely is ranking that 1). So logically, I need a mandatory question that will allow a minimum of 1 choice.
