custom editor for component

Hi all.
I'm trying to add a popup_list to a custom editor of my new component to initialize data.
I've managed to do it with a new Editor class :

Code (CSharp):

1.  
2.  
3. public class myscript : MonoBehaviour
4. {
5. public bool toto
6. ...
7. void Start()
8.     {
9. if (toto) { DoSomething; } else { DoSomethingElse; }
10. }
11. ...
12. }
13.  
14. [CustomEditor(typeof(myscript))]
15. public class myscriptEditor : Editor
16. {
17.     public enum OPTIONS
18.     {
19.         PARAM_INI_1= 0,
20.         PARAM_INI_2= 1,
21.     }
22.  
23.     public OPTIONS op;
24.    bool Type_CI;
25. public override void OnInspectorGUI()
26.     {
27.         DrawDefaultInspector();
28.         myscript myScript = (myscript)target;
29.  
30.         op = (OPTIONS)EditorGUILayout.EnumPopup("Type of Initial Conditions:", op);
31.         Type_CI = InstantiatePrimitive(op);
32.         if (Type_CI) { myScript.toto = true; } else { myScript.toto = false; }
33. }
34. bool InstantiatePrimitive(OPTIONS op)
35.     {
36.         switch (op)
37.         {
38.             case OPTIONS.PARAM_INI_1:
39.                 return true;
40.                 break;
41.             case OPTIONS.PARAM_INI_2:
42.                 return false;
43.                 break;
44.             default:
45.                 Debug.LogError("Unrecognized Option");
46.                 return false;
47.                 break;
48.         }
49.     }
50. }

The popup list works fine but the property named "toto" is also visible in the editor. I'd like to hide it as it an internal property. If I change it to private I can't modifiy it with my Editor class.
Thks for your help
