(Object, Component<Hierarchy>). Used as a kitchen sink Hierarchy component with optional Context Menu support. Hierarchies are recursive drag-and-drop lists with Groups and Items. Items and Groups may have separate Context Menus bound to them. Hierarchies are stored separately in main.hierarchies such that you can sync bindings between them.
The companion Object, Component<File> should be used if you intend on providing a custom file explorer to the user instead.
Note. ‘Returns:’ refers to what the Component value returns when exported to its .variable binding.
