I need to create the new button that allows to make the clone of buttons in the code below.

Please share some ideas, codes, links, scripts.

  using UnityEngine;
using System.Collections;

public class hibye: MonoBehaviour 
{

    public string slectedItem = "fd";
    private bool editing = false;



    private void OnGUI()
    {   
        if ( GUILayout.Button(slectedItem))
        {
            editing = true;
        }

        if (editing)
        {
            string[] sig = {"Banana","Apple","Orange"};

            for (int x = 0; x < sig.Length ; x++)
            {
                if (GUILayout.Button(sig[x]))
                {
                    slectedItem = sig[x];
                    editing = false;    

                }
            }
        }


                }
            }
