Nested Class Properties

You can now attach child properties to any class property and control exactly when they appear. Set a condition on the parent — such as when a specific value is selected — and the nested property shows up automatically. It stays hidden for every other selection. Annotators only see fields that are relevant to what they just labeled.

How it works:

• In the class editor, open any property and use Add Nested Properties to attach child properties to it.

• Each nested property appears when the parent is set or is any of a specific set of values.

• Mark any nested property as required independently of the parent.

• Keyframe behaviour inherits from the parent — consistent across the full hierarchy.

• Properties nest to any depth: a nested property can carry its own nested properties.

• Deleting a parent property removes all its children. A confirmation message lists what will be deleted before proceeding.
