I want to implement a ressource of the type Questionnaire. I want to have nested items like shown in this example: https://www.hl7.org/fhir/questionnaire-example-f201-lifelines.xml.html, which I can’t find where to implement in HL7 FHIR STU3. In this example it isn’t clear how the nested questions is implemented, whether item is sliced or what they do. How is this solved in STU3, when I am profiling using Forge?
Thanks in advance!
