EditorGUILayout.MaskField how to?

Heyo

I'm trying to figure out how I have to use EditorGUILayout.MaskField. I have a normal script, which I attach to a GameObject as Component.

In this script is a String[] which should hold all the selected data from MaskField.

I've created a CustomEditor class, this all works fine on other properties like Enum (single select) or other single select values.

My only problem ist the multi select (MaskField). What I have so far for the MaskField:

Code (CSharp):

1. int flag = EditorGUILayout.MaskField("Test", 0, allElements);
2.             for (int i = 0; i < allElements.Length; i++)
3.             {
4.                 int layer = 1 << i;
5.                 if ((flag & layer) != 0)
6.                 {
7.                     string selectedItem = allElements[i];
8.                 }
9.             }

In OnEnable I have the following:

Code (CSharp):

1. public void OnEnable()
2.     {
3.         elementsToColor = serializedObject.FindProperty("_elementsToColor");
4.  
5.     }

I also have this at the end of the script:

Code (CSharp):

1. serializedObject.ApplyModifiedProperties();

These is the propery from the Component script class.

Can someone please help me?
