When setting up a checklist, mark definitions also need to be set up. With a mark definition, the answers are set for specific questions within a checklist in the LEVIY app. Furthermore, within a mark definition it can be set whether an answer will have a mark if chosen. The height of the mark can be set by the user. Aswers can also be grouped together by means of a mark definition group. That group is then linked to a sub category and defines the specific answers that can be chosen for a specific question.
