EditorGUILayout.Foldout

Parameters

Returns

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

Description

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.
