Show rows Variables in a few lines, for each element with using unityEditor

Hi i create a custom property drawer. like this:

     public override void OnGUI (Rect position, SerializedProperty property, GUIContent label) {
         label = EditorGUI.BeginProperty(position, label, property);
         Rect contentPosition = EditorGUI.PrefixLabel(position, label);
         if (position.height > 16f) {
             position.height = 16f;
             EditorGUI.indentLevel += 1;
             contentPosition = EditorGUI.IndentedRect(position);
             contentPosition.y += 18f;
         }
         contentPosition.width *= 0.75f;
         EditorGUI.indentLevel = 0;
         EditorGUI.PropertyField(contentPosition, property.FindPropertyRelative("position"), GUIContent.none);
         contentPosition.x += contentPosition.width;
         contentPosition.width /= 3f;
         EditorGUIUtility.labelWidth = 14f;
         EditorGUI.PropertyField(contentPosition, property.FindPropertyRelative("color"), new GUIContent("C"));
         EditorGUI.EndProperty();
     }
