Add a clear, declarative option in Oracle APEX Tree Region to control single vs multiple node selection, with built-in examples and documentation.
Currently, developers must rely on properties or custom JavaScript to fully understand and manage multi-node selection behavior. Providing a more visible and well-documented option in the Tree Region settings—along with sample use cases—would improve usability, reduce development time, and help beginners adopt Tree components more easily.
This enhancement would be especially helpful for applications involving hierarchical data, role assignments, category selection, or navigation-driven workflows.
