Hi Darya,
let me give an example. I’m doing a survey.
The grid gives the options:
I’m a man.
I’m a woman.
The form will list two radioboxes requiring man or women checked.
however, there could be the third option in the grid: Secret.
For other problems, maybe there are more uncertain number of optoins. The problem is: How could all/partof these options(instead of one of these options) be listed in a form.
