The Hierarchy section is a tree view of all the items that are on the stage, arranged by their parent/child relationships.
Each row in the Hierarchy section represents an item on the stage. A circle button with an arrow appears next to items that have children nested under them. This button allows you to expand and collapse the list of children.
To change the parent/child relationships of objects you can either drag and drop, use the Pick Parent tool (press
P to active it), or use the Pick Child shortcut (press
C to active it).
Double click on a name to change it.
By default, toggling the visibility of an item also toggles the visibility of all its children.
To toggle only the visibility of the hovered item without affecting its children, hold
Cmd in Mac and
Ctrl in Windows while clicking the visibility icon.
Alt when clicking the visibility icon to hide all other items, apart for the hovered item and its children.
Lock items in the Hierarchy to prevent selecting them on the Stage. Locked items can still be selected in the Hierarchy.
Hover your mouse cursor over an item on the stage and press
H to scroll the Hierarchy to this item. This is a quick way to navigate the Hierarchy, particularly in very large files.
You can filter the entire contents of the Hierarchy Panel by pressing
F on Mac, or
F on PC.
