+# Design Proposal: Dynamic UI MFE Activation
+
+Author(s): UI Team
+
+Last updated: 11/24/2025
+
+## Abstract
+
+Currently, the Edge Orchestrator UI loads all Micro-Frontends (MFEs) regardless of whether they are needed by a
+specific user. This proposal describes a mechanism to explicitly enable or disable specific MFEs (Infra, Cluster
+Orch, App Orch, Admin) via configuration, making the UI dynamic and adaptable to different deployment scenarios.
+
+## Proposal
+
+The visibility and loading of different sections of the UI will be controlled by the `mfe` configuration in the Helm
+chart values.
+
+The values defined in `values.yaml` are injected into the application at runtime via the `runtime-config.js` file.
+The UI shell (`root` app) reads these values during bootstrap and dynamically constructs the routing and navigation
+menu.
+
+### Configuration
+
+To change which components are active, the `mfe` section in `apps/root/deploy/values.yaml` (located in the
+`orch-ui` repository) is used:
+
+```yaml
+mfe:
+  app_orch: true      # Controls Deployments tab/features
+  infra: true         # Controls Infrastructure tab/features
+  cluster_orch: true  # Controls Cluster Orchestration features
+  admin: true         # Controls Admin features
+```
+
+> **Note**: Currently, this configuration is managed directly within the `orch-ui` repository. In the future, we
+> plan to expose these controls through the Edge Manageability Framework (EMF) configuration, allowing for
+> centralized management of UI capabilities alongside other platform settings.
+
+### Effects
+
+When an MFE is disabled via this configuration:
+
+- **Navigation**: It will not appear in the main navigation menu.
+- **Routing**: Its routes will be disabled. Accessing the URL directly (e.g., `/applications/deployments`) will show
+  a "disabled" message instead of the application.
+- **Performance**: The application code for that MFE will not be loaded (lazy loading), reducing the initial bundle
+  size and load time.

+        alt MFE Enabled
+            router ->> mfe: Lazy Load Remote
+        else MFE Disabled
+            router ->> router: Render "Disabled" Placeholder
+        end
+    and Configure Navigation
+        app ->> nav: Render Layout
+        alt MFE Enabled
+            nav ->> nav: Show Menu Item
+        else MFE Disabled
+            nav ->> nav: Hide Menu Item
+        end
+    end
+```
+
+## Limitations
+
+- **Deployment Required**: Changing the enabled/disabled state of an MFE is a deployment-time configuration. It
+  requires a re-deployment to update the ConfigMap and restart the UI pod. It is not a user-facing toggle that can
+  be changed at runtime without a restart.
