**Purpose**: When enabled, displays an attribute from the parent page of the target entity instead of the target entity itself.

**Valid Values**:
- `false` (default): Display attribute from the target entity
- `true`: Display attribute from the target entity's parent page

**Use Case**: Useful for showing parent page attributes in child page layouts, such as displaying project-level information on task detail pages.

**Behavior**: Only takes effect when the target entity is a Page type. If `useParent=true` and the target entity has no parent, the behavior depends on the implementation.

**Note**: This parameter is hidden from the edit UI when the widget is embedded inside `cf.platform.attributesGroup`.
