Is is possible for menu to push down content?

Client likes the mega menu found on IBM.com where the menu pushes the content down instead of covering it. Is it possible to modify the menu to do this?

Hi
to modify it , yes. But I can't tell you how exactly as I have never tried to do this.Interesting idea, I will add this in my todo list. If you have some explanations on how to do this, you can post in in the forum if you try to do it yourself

I've tried changing absolute & relative positioning, z-indexes, and a few other things in the CSS. However, it appears the solution is much more complex given that z-indexes are dynamically generated and placed on the list items.

of course the solution is complex however I would already have given you the wey to do it. Also the JS has to be hacked
