Discussion Custom Editor Enum Dropdown to display vars, but with a custom object?

I followed a few guides which works well with types like string, int, float, bool etc... but if I have lets say my own type (InteractSteps) which englobes an int and a string, it doesn't work.

As of right now, it doesn't do anything.

Basically, I want this:


Here's my Custom Editor code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. #if UNITY_EDITOR
6. using UnityEditor;
7. #endif
8.  
9. [CustomEditor(typeof(InteractActionableState))]
10. public class InteractActionableStateEditor : Editor
11. {
12.     public EnumInteractActionableMode categoryToDisplay;
13.  
14.     public override void OnInspectorGUI()
15.     {
16.         base.OnInspectorGUI();
17.         categoryToDisplay = (EnumInteractActionableMode)EditorGUILayout.EnumPopup("ModeAnimation", categoryToDisplay);
18.  
19.         EditorGUILayout.Space();
20.  
21.         switch (categoryToDisplay)
22.         {
23.             case EnumInteractActionableMode.Animator:
24.                 DisplayAnimator();
25.                 break;
26.  
27.             case EnumInteractActionableMode.Transforms:
28.                 DisplayTransform();
29.                 break;
30.         }
31.  
32.         serializedObject.ApplyModifiedProperties();
33.     }
34.  
35.     void DisplayAnimator()
36.     {
37.         EditorGUILayout.PropertyField(serializedObject.FindProperty("animClip"));
38.         EditorGUILayout.PropertyField(serializedObject.FindProperty("AnimationGameObjectWithScriptToRun"));
39.     }
40.  
41.     void DisplayTransform()
42.     {
43.         EditorGUILayout.PropertyField(serializedObject.FindProperty("Transforms"));
44.     }
45. }

And here's my object code:

Code (CSharp):

1. using System;
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.Events;
6.  
7. [Serializable]
8. public class InteractActionableState
9. {
10.     [Space(10)]
11.     [Header("=== Global ===")]
12.     public GameObject requiredObjectForInteract;
13.     public bool requiredObjectInHand = true;
14.     public AudioClip soundOfState;
15.     public bool DoExternalEventsDuringMovement = false;
16.     public UnityEvent ExternalObjectExecuteFunction;
17.     public EnumInteractActionableMode ModeAnimation;
18.  
19.     [Space(10)]
20.     [Header("=== Mode Animation: Animator ===")]
21.     public AnimationClip animClip;
22.     public UnityEvent AnimationGameObjectWithScriptToRun;
23.  
24.     [Space(10)]
25.     [Header("=== Mode Animation: Transform ===")]
26.     public List<InteractionStep> Transforms = new List<InteractionStep>();
27.  
28.     public void TriggerExternalEvents()
29.     {
30.         ExternalObjectExecuteFunction.Invoke();
31.     }
32. }
