How to relocate components dynamically?

I have a series of TextAreas folded with EditorGUI.Foldout. This works fine but I would like to push the following foldouts when I open one above them. So I use an array of Rect when I create them so I could hopefully modify those making components move but it doesn't seem to work.

I'm a unity3d and C# newbie so bare with me with the code:

     using UnityEngine;
     using UnityEditor;
     using System.Collections;
     
     public class PageViewer : MonoBehaviour {
         public float x;
         public float y;
         //Store the field values for CRUD operations.
         private string[] variables = new string[]{
             "",
             "",
             "",
             "",
             ""
             };
         //This handles the collapsable status for each field.
         private bool[] status = new bool[]{
             false,
             false,
             false,
             false,
             false
         };
         //Position of fields for dynamic display.
         private Rect[] positions = new Rect[]{
             new Rect(),
             new Rect(),
             new Rect(),
             new Rect(),
             new Rect()
         };
         public int gap;
         public float height;
         public float width;
         public Page original, mod;
         private Vector2 scrollPosition;
     
         // Use this for initialization
         void Start () {
         }
     
         private void OnGUI(){
             float newy = y + gap;
             int index = 0;
             
             createEditableTextArea(x, newy, gap, width, 30, "X", index++);
             
             newy += gap * 2 + 30;
             createEditableTextArea (x, newy, gap, width, height + 120, "Y", index++);
             
             newy += gap * 2 + height + 120;
             createEditableTextArea (x, newy, gap, width, height, "Z", index++);
             
             newy += gap * 2 + height;
             createEditableTextArea (x, newy, gap, width, height, "A", index++);
             
             newy += gap * 2 + height;
             createEditableTextArea (x, newy, gap, width, height, "B", index++);
             }
     
         public void createEditableTextArea(float x, float y, int gap, float width, 
                                            float height, string description,int index){
             positions [index] = new Rect (x, y, width, height);
             status [index] = EditorGUI.Foldout (new Rect (x - gap, index * 30, width
                             + (gap * 2), 30), status [index], description);
             if (status [index]) {
                 GUI.Box (new Rect (x - gap, y - gap, width + (gap * 2), 
                                    height + (gap * 2)), description);
                 variables [index] = GUI.TextArea (positions [index], 
                                       variables [index]);
                 Debug.Log("Opened: "+description);
                 //Move the following fileds down
                 for(int i=index+1;i<positions.Length;i++){
                     float ny=y+height+gap;
                     Debug.Log("Updating position index: "+i+" from: "+positions[i].y+" to: "+ny);
                     positions[i].x=0;
                 }
             } 
         }
 }

I was expecting the components to move to x=0 but nothing happened. Any idea?
