umbraco-menu-items

To add custom menu items to the Umbraco backoffice, you implement link, action, or tree-type items using the Umbraco extension manifest system. This extends backoffice navigation by adding custom links and action triggers to predefined menus.

For Umbraco UI development, you can create three types of custom menu items: link, action, and tree. Link items point to URLs, action items trigger specific processes, and tree items integrate nested navigation structures into existing backoffice menus.

Yes, you can use TypeScript to implement custom action triggers in Umbraco menus. Custom action menu items optionally require custom element or action implementations, allowing you to define specific behaviors using TypeScript within the extension manifest system.

The Umbraco extension manifest system works for backoffice customization by defining custom menu items that integrate into existing menus or create new ones. It facilitates UI extension by mapping predefined menus to custom navigation links and action triggers.

You optionally need custom element implementations to extend Umbraco with action menu items. While the manifest system handles the menu structure, custom elements or action implementations are required to define the specific behavior triggered when editors interact with the action.
