umbraco-menu-items

To add custom Umbraco backoffice menu items, you generate a manifest defining the alias, meta (label/icon/menus), and kind-specific properties, then optionally wire actions or Lit custom elements for rendering.

Umbraco menu item kinds dictate behavior: link kinds navigate to a URL, action kinds trigger UmbMenuItemAction execution logic, and tree kinds render hierarchical navigation structures within specific backoffice menus.

Implementing an UmbMenuItemAction requires defining the action manifest structure and wiring the execution logic in TypeScript, mapping the official Umbraco documentation requirements to the correct extension registry components.

Yes, you can render optional custom elements in Umbraco backoffice menus by building Lit-based components and registering them through the extension registry alongside your menu item manifests.

TypeScript is used to map official Umbraco documentation requirements into working extension structures, generating manifests, action execution code, and optional Lit element rendering for backoffice menu items.

The best way to structure an Umbraco menu extension manifest is to include the required alias, meta fields like label and icon, menus list for navigation targeting, and kind-specific properties based on official documentation.
