    Before: 
    1. Set Show Btn Count In Your Prefab
    2. BtnItem GameObject: Tag => CommonUtilsMenu
    Tips:
    1. require("Base/UIHelper.lua"):AddScript(menuBox, "CommonUtils/Menu/Menu.lua")
    2. If Need:
        2.1 Set Show Btn Count: nShowBtnCount => Odd Number 
        require("CommonUtils/Menu/Menu.lua").SetShowItemData(nShowBtnCount)
        2.2 Set Can Mouse Scroll Control
        require("CommonUtils/Menu/Menu.lua").SetMenuScroll()
