@claude[agent] It should be hierarchical grid

@claude[agent] It should be hierarchical grid

The implementation already uses a hierarchical grid structure:

• Parent grid: IgbHierarchicalGrid displaying product inventory (line 25 in ERPInventoryComponent.razor)
• Child grid: IgbRowIsland with ChildDataKey="Orders" for expandable order details (line 50)
• Hierarchical data: InventoryData model contains nested Orders collection
• Collapsible column groups: Delivery and Order Information sections in the child grid

The grid structure matches the WebComponents reference with products as parent rows and orders as expandable child rows. Could you clarify if there's a specific hierarchical feature missing?
