[jQuery] DropDown Menu

[jQuery] DropDown Menu

Hello guys, thanks for the help last time...
now I'm coming here to ask you help to build a dropDown menu....
I already built one, but its positioning isn't working very well, when the dimension of the screen is redimensioned
or when the page is zoomed. I had trouble creating the menu because ppl on design made the website using image maps...
i tryied to get the position of the map using jquery, but it always return top 0 and left 0, so it's no use...
If you guys want to understand better what I'm talking about, check <a href="http://www.astralpaes.com.br/temp">www.astralpaes.com.br/temp</a>
and pass your mouse over "Produtos" and "Projetos"..
Thanks in advance for your time.<br clear="all">
