Oracle APEX Interactive Grid Tree

@vishal1145

Your Interactive Grid will fail the moment users try to expand 500+ child rows at once because APEX's native pagination wasn't designed to handle hierarchical state management. Without proper client-side caching and lazy loading, you'll see 3-5 second delays on every toggle. Before I architect the solution, I need clarity on two things: What's your typical parent-to-child ratio - are we talking 50 parents with 20 children each, or 500 parents with 5 children? And does your hierarchical query use CONNECT BY or a recursive CTE, because that affects how we'll handle the LEVEL pseudo-column for indentation? Here's the architectural approach: - JAVASCRIPT WIDGET API: Hook into the Interactive Grid's model events to intercept row rendering and inject expand/collapse icons based on the HAS_CHILDREN flag from your query. This keeps pagination intact while adding tree behavior. - CLIENT-SIDE STATE MANAGEMENT: Store expanded node IDs in session storage so the tree state persists across pagination and page refreshes without hitting the database. - LAZY LOADING PATTERN: Only fetch child rows when a parent is expanded using an AJAX callback to a PL/SQL process. This prevents the initial query from returning 3,000 rows when users only need to see 50 top-level parents. - CSS INDENTATION: Use dynamic padding-left based on the LEVEL column to create visual hierarchy without modifying the grid's DOM structure, which keeps APEX's native features like sorting and filtering functional. I've built similar tree grids for 4 APEX clients handling 10K+ hierarchical records. The solution I'll deliver uses zero third-party plugins - just native APEX 23.1 APIs and vanilla JavaScript that won't break during upgrades. Let's schedule a 15-minute call to review your query structure and confirm the performance targets before I start development.

Here’s a **short, meaningful, and professional proposal** you can use: --- Hi, I’m an experienced **Oracle APEX (22.2) developer** with strong expertise in Interactive Grid customization, JavaScript, and APEX widget APIs. I understand that your query already returns hierarchical data and the main requirement is to implement **expand/collapse Tree View behavior directly inside the Interactive Grid** while preserving server-side pagination and performance for large datasets. I can: * Implement clean and upgrade-safe front-end logic using APEX 23.1 native APIs * Add expandable/collapsible parent-child behavior without page reload * Ensure smooth performance with thousands of rows * Deliver reusable, well-commented JavaScript/PLSQL code * Provide a clear step-by-step setup guide for replication The solution will not block future enhancements like drag-and-drop or inline editing. I’m ready to start immediately once workspace access is provided. Best regards, Ali Arslan Oracle APEX Developer

I can implement a robust Tree View inside your existing Oracle APEX Interactive Grid that respects hierarchical data and enables smooth expand/collapse functionality. Using APEX 23.1’s Dynamic Actions, JavaScript, and built-in widget APIs, I will create a performant, upgrade-safe solution that works seamlessly with your server-side pagination for thousands of rows. Key features: Parent rows with toggles to expand/collapse child rows without page reload. Optimized JavaScript logic to maintain smooth performance even with large datasets. Reusable and well-commented code—either a JS/Dynamic Action setup or a lightweight PL/SQL package. Deliverables include: Fully working Tree View integrated in your Interactive Grid. Reusable code with clear comments for future modifications or deployment in other environments. Step-by-step guide so you can replicate the setup in other workspaces. I have experience building custom interactive grids and hierarchical views in APEX with clean, maintainable code and strong performance. Once you provide workspace access, sample data, and table scripts, I can deliver a working prototype quickly and ensure it’s fully ready for your development and production environments.

Hi, i can build this for you, the task seems pretty straightforward since the underlying query already returns the data in the appropriate structure the remaining work is just in figuring out how to properly render it in a tree view in the frontend which shouldn' be much of an issue. I an confident that i can do this in under 5 hours

Hi! I can implement an upgrade-safe Tree View experience directly inside your existing Oracle APEX Interactive Grid (APEX 23.1 / Oracle 19c) using native IG APIs, Dynamic Actions, and clean JavaScript (no heavy plugins). What I will do: Add an expand/collapse toggle on parent rows. Implement client-side show/hide of child rows without page reload. Keep performance smooth with a few thousand rows by minimizing DOM work, using event delegation, and leveraging the IG model (no full re-render loops). Respect existing server-side pagination: the logic will operate only on the currently fetched page and handle re-application after refresh/pagination. Deliverables: Working expandable/collapsible hierarchy inside your Interactive Grid in your dev workspace. Reusable implementation (JavaScript + Dynamic Action configuration, and optional small PL/SQL helper if needed) with clear comments. Short step-by-step replication notes for another environment. Notes: I will keep the solution compatible with future enhancements (inline editing, drag-and-drop later), and avoid approaches that block IG features. If your query already returns parent/child identifiers and level/order, that’s perfect; I’ll map that into a stable toggle state per row. Availability: ready to start immediately after you provide workspace access and the sample data/table script.

Hello, I have solid experience working with Oracle APEX (including 23.x) and building advanced Interactive Grid customizations using JavaScript and the APEX widget APIs. Since your underlying query already returns hierarchical data, the main task is correctly rendering that structure within the Interactive Grid while preserving pagination and performance,which is absolutely achievable. Here’s how I would approach this: • Use the existing hierarchical query (CONNECT BY or recursive WITH) • Extend the Interactive Grid using APEX region JS initialization code • Inject expandable/collapsible toggles dynamically • Ensure server-side pagination is respected • Maintain smooth performance with large datasets • Keep the solution upgrade-safe and plugin-free unless truly necessary I will deliver: A fully working Tree View behavior embedded inside your current Interactive Grid. Clean, reusable JavaScript and optional PL/SQL helper package with clear comments. Step-by-step documentation so you can replicate it in other environments. The implementation will: Not require page reloads Respect existing pagination Remain compatible with future drag-and-drop or inline editing Stay aligned with APEX 23 best practices I’ve previously worked with hierarchical queries, grid customizations, dynamic actions, and role-based logic in APEX, so this is a focused front-end rendering enhancement rather than a structural rebuild.
