Customizing the Tree Report in Oracle APEX allows developers to tailor the hierarchical data display to meet specific user needs and improve overall usability. By adjusting attributes such as node labels, icons, and expand/collapse behavior, you can create a more intuitive and visually appealing interface. Customization also includes modifying the SQL query to control the data structure and adding dynamic actions or styles to enhance interactivity and presentation.
After creating the tree, you can customize how it appears and behaves.
Configuring Tree Attributes
Open Page Designer and select the Tree Region in the Rendering Pane.
Modify the following attributes under the Tree Attributes section:
Icon Column: Specify an icon for nodes (e.g., fa-folder for parent nodes).
Expand All: Enable this if you want the tree fully expanded by default.
Lazy Loading: Set this to Yes if working with large datasets to improve performance.
Selection Type: Choose Single Selection if you want users to select only one node.
In conclusion, customizing the Tree Report empowers you to present complex hierarchical data in a clear and user-friendly way within Oracle APEX. With careful configuration and styling, your tree structures can better reflect business requirements and offer users a seamless navigation experience. Taking advantage of these customization options ensures your applications are both functional and visually engaging.
