Hi,
I would like to create a grid questions with 5 columns and 4 rows, using radio buttons as answer options, but only one option can be selected in the whole grid/matrix - not one per row.
How do I do this? And is it possible to add a none to this as well? That would result in basically 21 possible answers to select from but at least 20 of them need to be shown in a grid.
Thank you for the help,
Mareike
