Summary

The dynamic-plugins.yaml file in the redhat-resource-optimization plugin uses a children structure for hierarchical menu items that does not work with RHDH dynamic plugin loader.

Problem

The dynamic-plugins.yaml (added in commit 9e1f179b / PR #1719) defines the menu structure as:

menuItems:   cost-management:     text: Cost management
    icon: costManagementIcon
    children:       openshift:         text: OpenShift
        route: /resource-optimization/openshift
      optimizations:         text: Optimizations
        route: /resource-optimization

This children structure with nested route properties is not parsed by RHDH dynamic plugin loader. When applied, the menu items do not appear.

Root Cause

The Root.tsx in the static Backstage app uses a custom React component CollapsibleSubmenu to create the hierarchical menu. The dynamic-plugins.yaml was written to mirror this structure conceptually, but RHDH dynamic plugin system uses a different approach.

Working Configuration

RHDH dynamic plugin system requires:

1. menuItem inside each dynamicRoute to define the menu text
2. menuItems section using parent property to link children UP to parents
3. Menu item IDs derived from route paths (e.g., redhat-resource-optimization.ocp for /redhat-resource-optimization/ocp)
4. Parent menu items use title not text

dynamicRoutes:   - path: /redhat-resource-optimization
    importName: ResourceOptimizationPage
    menuItem:       icon: costManagementIcon
      text: Optimizations
  - path: /redhat-resource-optimization/ocp
    importName: OpenShiftPage
    menuItem:       icon: costManagementIcon
      text: OpenShift
menuItems:   redhat-resource-optimization:     parent: cost-management
    priority: 10
  redhat-resource-optimization.ocp:     parent: cost-management
    priority: 20
  cost-management:     icon: costManagementIcon
    title: Cost management
    priority: 100

Impact

Users following the plugin dynamic-plugins.yaml configuration will not see the Cost management menu or its children in RHDH.

Suggested Fix

Update dynamic-plugins.yaml to use the parent property approach that works with RHDH dynamic plugin loader.
