    , create a folder named Editor.

  3. In the Editor folder, create a C# script file named ToggleExample with the following content:

    using UnityEngine;
    using UnityEditor;
    using UnityEngine.UIElements;
    namespace Samples.Editor.Controls
    {
        public class ToggleExample : EditorWindow
        {
            private Toggle showToggle;
            private Toggle activateToggle;
            private Label labelToShow;
            private Button buttonToActivate;
            [MenuItem("Window/ToggleExample")]
            public static void OpenWindow()
            {
                var window = GetWindow<ToggleExample>("Controls: Toggle Sample");
                window.minSize = new Vector2(200, 170);
                EditorGUIUtility.PingObject(MonoScript.FromScriptableObject(window));
            }
            public void CreateGUI()
            {
                showToggle = new Toggle("Show label")
                {
                    value = true
                };
                activateToggle = new Toggle("Active button")
                {
                    value = true
                };
                labelToShow = new Label("This label is shown when the above toggle is set to On");
                buttonToActivate = new Button(() => Debug.Log("Button pressed!"))
                {
                    text = "Active if above toggle is On"
                };
                rootVisualElement.Add(showToggle);
                rootVisualElement.Add(labelToShow);
                rootVisualElement.Add(activateToggle);
                rootVisualElement.Add(buttonToActivate);
                showToggle.RegisterValueChangedCallback(evt => labelToShow.visible = evt.newValue);
                activateToggle.RegisterValueChangedCallback(evt => buttonToActivate.SetEnabled(evt.newValue));
            }
        }
    }
    
  4. To try the example, from the menu, select Window > ToggleExample.
