Drop-down menu hidden behind CSS frames layout

[Nosilence]

Hello to all !!

I'm new here and a real beginner in webprogramming. I found this great site by searching for help to my probs.
For our company i start to realize a website last year - and now i try to make a "lifting" to this site.
I found here some great program-code i like to use at same time, but with problems and i hope to find some help...
I try to use the "CSS Left and Top Frames Layout"
http://www.dynamicdrive.com/style/la...frames-layout/
and the "SuckerTree Vertical Menu (v1.1)"
http://www.dynamicdrive.com/style/cs...menu-vertical/
in the "left framecontent". The problem is, that the sub-menu is hidden behind the "mainframe". I found the solution to ad to the frames a "z-index" and it works perfect. But now when i put an "overflow: auto" to the left frame to can see all on smal screens, the sub-menu is again hidden behind all.
Here the link to my website: www.inno4.com/newsite
Hope someone can help me...
Thanks

Hi Beverleyh !!

Thanks to have a look on my big problem.
The problem i discribe, i have it on entire site:
http://www.inno4.com/newsite/html-fr/Accueil-FR.html
You can see on the left side the menu, but the sub-menu in GALERIE, CONTACT,... are hidden behind the main content. I only change in the CSS file (http://www.inno4.com/newsite/css/inno4-2010.css) the "overflow" from "visible" to "auto" and since i can't see anymore my sub-menu.

#framecontentLeft, #framecontentTop{
position: absolute;
top: 0;
left: 0;
width: 220px; /*Width of left frame div*/
height: 100%;
overflow: auto; /*Disable scrollbars. Set to "scroll" to enable or "hidden" to disable or "auto" for automatic*/
background-color: #A60323; /* Blau #045C97 */
text-align: center;
z-index: 15;
}


Wait for some help
Thanks
