在滚动列表中再次插入一个滚动列表，实现能点击收放

描述：在一个滚动列表中，再次插入一个滚动列表。 实现点击上层滚动列表中的按钮，让他的子物体显示出来并使得整个滚动列表的Content放大，再次点击实现收缩，并使得整个滚动列表的Content缩小。

 

操作内容如上图：

下面是添加在ClubItems上的脚本：

using System.Collections;

using UnityEngine.UI;

    public RectTransform ClubItemsTrans;
    public RectTransform ContentTrans;

    private float contenHeight;        //获得content当前的高度

    public GameObject clubItem;

        clubItemHeight = ClubItemsTrans.sizeDelta.y;

        for (int i = 0; i < 11; i++)
        {

        }
        TheClubHeightAdd(11, ParentTrans.childCount);
