Umbraco Tree Item

This handles tree item rendering in Umbraco's backoffice navigation. You'll use it when building custom entity types that need to appear in sidebar trees, though most of the time you can stick with `kind: 'default'` and skip writing custom contexts entirely. Only bother with a custom context if you need dynamic icons, badges, or special click behaviors. The skill emphasizes fetching fresh docs first (trees in Umbraco 14+ work differently than older versions) and provides minimal working examples for both basic manifests and custom contexts extending UmbDefaultTreeItemContext. Keep tree items lightweight since they can multiply quickly in large content trees.

Umbraco Tree Item

What is it?

Tree Items define how entities are rendered in tree structures throughout the Umbraco backoffice. They control the visual representation and behavior of items in sidebars and navigation trees. Tree items are associated with entity types and can be customized to display additional information, icons, or custom rendering for specific entity types.
