I want that my dce experiment once the surveyers choose one option they cannot be able to select again or change it
Do you want to
a) disable the “Prev” button such that respondents cannot return to the page after they have clicked “Next”
b) make the options unclickable after an alternative has been selected, but stay on the same page
c) proceed to the next page as soon as an option is selected?
a) can be set on the Layout page of the survey; b) and c) can be implemented using JavaScript.
