# Merged With Ecommerce

Demonstrates `XWUISuperApp.merge(XWUISuperInventory, XWUISuperEcommerce)` against the already-shipped Ecommerce shell. Inventory is mounted as the host class so its title and branding survive; because the host already contributes its own `menuTree()`, the merged tree is filtered to `n.key !== "inventory"` before being fed back as `extraTree` (otherwise the Inventory accordion would render twice). Inventory is listed first so `inv-dashboard` stays the cold landing leaf, and the Ecommerce leaves appear under the Inventory group in the merged sidebar.
