26 Feb 2010 — Here's something that we've had requests for from users, and has just emerged from our developers. You can now add a "None of these" or "No opinion" radio button option to the end of each row of a multiple choice matrix. Take a look at this example:

If selected, it will untick any previously ticked answers in the row. It works in exactly the same way as the "None of these" option at the end of a standard multiple choice question works. It is particularly useful where a matrix question is compulsory and respondents don't want to answer one, or all, of the rows. This option can also be pre-selected if desired. Please use the Helpdesk ticket system to feedback any comments or questions you may have.
