Anyone know how to get a menu like this site

Hi,

Can any one provide me with an idea of how this menu was made. I am not getting the actions to work properly. I have made the text menu buttons like in the site and they are that small. I have a hit button at the bottom most layer which has an action script assigned to it which calls the on(rollOver) event the menu has to increase. and when I rollOut the menu has to decrease. What is happening with my action script is that when the text buttons become big, then automatically they take up the entire space, so the moment the mouse arrow goes over the text links, the animation goes back to being small. Is there a way to control this. Where should I put the actions for the menu.

oh, the menu should function like http://www.moet.com

Thanks for all the help
