Adding a menu under a curl effect

Hey Everyone.

Im needing some help on how i can add a menu navigation under my page curl **button **effect. So when the user rolls over the corner the page curls up and out comes the menu, where you can click on and so on.

I can only get to the stage where i have the menu in place and it comes up under the curl, but when i want to click onto the menu links i cant, because of the curl effect button. Its like a button on top of a button, they just clash into each other.

Is there any way i can work around this.

Any help would be amazing…please please…

Many thanks
