Unity Engine

Hi all,
I want to hide these fields in the inspector and if I need to change them I want to show them with an arrow button or something like that. How can I do it?

Look up custom editor/inspectors.

the code below works fine with an integer field.
Can you tell me how can I turn it to hide the field " Material myMaterial; " or GameObject MyObject

 public class MyScript : MonoBehaviour
{
   public bool flag;
   public int i = 1;
}
[CustomEditor(typeof(MyScript))]
public class MyScriptEditor : Editor
{
   void OnInspectorGUI()
   {
     var myScript = target as MyScript;
     myScript.flag = GUILayout.Toggle(myScript.flag, "Flag");
   
     if(myScript.flag)
       myScript.i = EditorGUILayout.IntSlider("I field:", myScript.i , 1 , 100);
   }
}
