Need Help with Suckertree Horizontal menu

[Jacques]

1) Script Title: SuckerTree Horizontal Menu

2) Script URL (on DD): http://www.dynamicdrive.com/style/csslibrary/item/suckertree-menu-horizontal/

3) Problem:
Hi,
I'm currently having problem with SuckerTree Horizontal Menu dropdown in the demo below.

Demo page: http://vivaideas.com/vivaviva/demo/demo.htm

I was combining the sliding door technique with suckertree dropdown which was working fine till I came to the dropdown menu portion. It seems fine for the 1st menu but when it goes to the second one, the submenu went underneath the content below, making it hidden.

I've tried using z-index but the problem still persist. Can anyone enlighten me on what and where I've went wrong with the implementation of this code.

Thank in advance for everyone's kind attention and assistance. Very much appreciated for the help

It seems that the one causing the problem is the flash animation(.swf) below the menu, nonetheless I still can't pinpoint the where exactly make the flash appear at the back of the menu dropdown instead of the menu dropmenu going underneath it.
