The Feature will be enabled/disabled for a particular category using the flag “allowBranching“ with the value “Yes/No“
The flag allowBranching will be stored at object level schema with default to “No“ and same can be overridden for specific category at category definition level.
A dependent question can be added only for questions available within the immediate parent. It means we can't target question available with other parents within observation/survey hierarchy.
The rule (branchingLogic) will be available with the immediate parent (section or root node)
The branchingLogic will be stored
in the hierarchy itself, if available at section/unit level.
in the hierarchy & graph, if available at root level (Observation/Survey)
“branchingLogic“ will be added to QuestionSet object level schema as an optional property.
“branchingLogic” will be accepted by the platform only if “allowBranching” is set “Yes”.
Sample value of branchingLogic is as below:
