Extension: choiceOrientation

URL for this extension:

http://hl7.org/fhir/StructureDefinition/questionnaire-choiceOrientation

Status: draft. Extension maintained by: HL7

Identifies the desired orientation when rendering a list of choices (typically radio-box or check-box lists).

Comment:

Systems may choose to wrap answers rather than attempting to display them all in one row or column. Language conventions may determine the order in which the choices are listed (left-to-right or right-to-left, etc.).

Context of Use: Use on Element ID Questionnaire.item or Element ID Questionnaire.item.item, with Context Invariant = type='choice' or type='open-choice'
