Custom ShaderGUI reference

Hi,
Looking for some reference for writing custom ShaderGUI's for shaders made in shader graph like combining properties in dropdown menus etc. in inspector view
This:
https://docs.unity3d.com/Manual/SL-CustomShaderGUI.html
isn`t very helpfull and im having issues to find working samples, nothing i've tried worked...


This is my latest attempt:

Code (CSharp):

1. public class ShaderGUI_Skybox : ShaderGUI
2. {
3.     override public void OnGUI(MaterialEditor materialEditor, MaterialProperty[] properties)
4.     {
5.  
6.         bool showstuff = false;
7.  
8.         base.OnGUI(materialEditor, properties);
9.         EditorGUI.BeginChangeCheck();
10.  
11.         if (GUILayout.Button("Select GUI Color"))
12.         {
13.             showstuff = !showstuff;
14.             Debug.Log(showstuff);
15.         }
16.  
17.  
18.         if (EditorGUI.EndChangeCheck())
19.         {
20.             Debug.Log("End");
21.             if (showstuff)
22.             {
23.                 // Sun
24.                 EditorGUILayout.LabelField("Sun", EditorStyles.boldLabel);
25.                 string[] SunReferences = { "_SunScale", "_SunConvergence", "_SunIntensity" };
26.                 foreach (string Reference in SunReferences)
27.                 {
28.                     MaterialProperty SunReference = ShaderGUI.FindProperty(Reference, properties);
29.                     materialEditor.ShaderProperty(SunReference, SunReference.displayName);
30.                 }
31.             }
32.         }

Debug.Log works but the GUI in inspector does nuthing and im totally lost ...

 

Got it,
EditorGUILayout.BeginFoldoutHeaderGroup(true, "Dropdown");
and
EditorGUILayout.EndFoldoutHeaderGroup();
creates the dropdown menu i was looking for

Code (CSharp):

1.  
2. public class ShaderGUI_Skybox : ShaderGUI
3. {
4.     bool showPosition = true;
5.     string status = "Settings";
6.  
7.     override public void OnGUI(MaterialEditor materialEditor, MaterialProperty[] properties)
8.     {
9.         showPosition = EditorGUILayout.BeginFoldoutHeaderGroup(showPosition, status);
10.  
11.         if (showPosition)
12.         { // Sun
13.             EditorGUILayout.LabelField("Sun", EditorStyles.boldLabel);
14.             string[] SunReferences = { "_SunScale", "_SunConvergence", "_SunIntensity" };
15.             foreach (string Reference in SunReferences)
16.             {
17.                 MaterialProperty SunReference = ShaderGUI.FindProperty(Reference, properties);
18.                 materialEditor.ShaderProperty(SunReference, SunReference.displayName);
19.  
20.                 //EditorGUILayout.Separator();
21.             }
22.  
23.         }
24.         EditorGUILayout.EndFoldoutHeaderGroup();
25.     }
26. }
27.
