the elements multiple choice (radio button), dropdown and checkbox allow you to define lists of values of which an answer can be selected.

To facilitate analysis of your study data exports, either in SAS or Excel format,it is possible to not only create answer values (code list), but to also assign a value to each code list item.
  • multiple choice and dropdown = single select
  • checkbox = multi select

Manually assigned code list values do not need to be consecutive, they should however be numeric (positive, starting from 0) and should be unique within the codelist. Codelist values do not need to be unique between codelists.
