All the questions of the questionnaire are mandatory by default, so an answer is always required in order to proceed with the interview.
To deactivate this setting from the “Questions management” page you will have to click on the gearwheel button of the question and disable the “Mandatory answer” option.
In matrix questions you will find the “Make all optional” button that will disable all the answer options in all matrix rows or 3D matrix cells.
If needed, you can change the settings of one or more single rows or cells by clicking on their “Settings” button and selecting “Mandatory answer”.
