Umbraco Manifest Picker
This helps Claude implement Umbraco's `umb-input-manifest` component, which is basically a dropdown picker for registered backoffice extensions. You'd use it when building configuration UIs where users need to select from workspaces, dashboards, property editors, or any other extension type in the registry. The skill includes two solid examples: a basic picker locked to one extension type, and a dynamic browser that lets you filter by type first. It's narrowly focused but genuinely useful if you're building admin screens that reference other parts of the Umbraco backoffice. The extension types table is handy reference material.

Umbraco Manifest Picker
What is it?
The <umb-input-manifest> component provides a picker UI for selecting registered extensions from the Umbraco extension registry. It allows users to pick from any extension type (workspaces, dashboards, property editors, etc.) and returns the selected manifest. This is useful for configuration UIs where users need to reference other extensions.
Documentation
Always fetch the latest docs before implementing:
- Extension Registry: https://docs.umbraco.com/umbraco-cms/extend-your-project/backoffice-extensions/extending-overview/extension-registry
- Foundation: https://docs.umbraco.com/umbraco-cms/extend-your-project/backoffice-extensions/foundation
Reference Example
The Umbraco source includes a working example:
Location: /Umbraco-CMS/src/Umbraco.Web.UI.Client/examples/manifest-picker/
This example demonstrates a dashboard that lets users browse and select extensions by type.
