반환

bool The foldout state selected by the user. If true, you should render sub-objects.

설명

Make a label with a foldout arrow to the left of it.

This is useful for creating tree or folder like structures where child objects are only shown if the parent is folded out.


Create a foldable menu that hides/shows the selected transform.

// Create a foldable menu that hides/shows the selected transform position.
// If no Transform is selected, the Foldout item will be folded until
// a transform is selected.
