Treemenu User Area

HI, following Scriptcase video tutorial on YouTube (keywords: scriptcase user area) it is ok for Menu application but no luck for Treemenu application, even the CSS class has been changed from scMenuHHeader to be scMenuTHeader, copying from “mainmenu” Header HTML Templates.

The problem is the pop-up User Area is truncated by main area of Treemenu iframe. I’ve tried to change the pop-up’s CSS z-index to be 9999 but still no luck. Please advise.
