# Hierarchy window

> View and manage the objects in your scene in a hierarchical structure.

View and manage all the objects in your scene.

The **Hierarchy** window displays every [GameObject](/engine/6000.6/manual/working-with-gameobjects/game-objects.md) in a scene, including models, cameras, and [prefabs](/engine/6000.6/manual/working-with-gameobjects/prefabs.md). You can use the **Hierarchy** window to manage and group the GameObjects you use in a scene. When you add or remove GameObjects in the Editor view, you also add or remove them from the **Hierarchy** window.

You can open more than one scene in the **Hierarchy** window at the same time, with each scene containing its own GameObjects. To learn more, refer to [Work with multiple scenes in Unity](/engine/6000.6/manual/working-with-scenes/multi-scene-editing.md).

The **Hierarchy** window can also display items that aren't GameObjects, such as UI Toolkit visual elements. To learn more about displaying visual elements in the **Hierarchy** window, refer to the [Reference visual elements](/engine/6000.6/manual/uitoolkits/uielements/uie-support-for-runtime-ui/reference-visual-elements-in-inspector.md#enable-hierarchy-integration).
