I need a css dropdown menu on my services nav [login to view URL] when you mouse over the services nav link it must bring up a dropdown that looks the same as scriptlances dropdown menus i tried to do it but my CSS goes all weird when i try. the font and site look must stay exactl the same i just want to add a drop down. just call the drop down links temp1,temp2,temp3 now, i will add my own links in there. I also want sublinks like scriptlance. go to support>mytickets on scriptlance for an example Thanks Jaco
