How do I make my wordpress menu have a drop down feature?

say I have a page called "Surfaces" that shows on the menu at the top, I want to be able to scroll over that and have more options.

Thanks

yeah, I got it as soon as I asked ha ha, thanks for the quick response! I'm not use to that lol.

Thanks

Hi,
to align the main wordpress menu to center please find this code in style.css:

.topmenu {
height: 35px;
z-index: 1300;
font-family: 'MelbourneRegular', Arial, sans-serif;
font-size: 16px;
}

.topmenu {
height: 35px;
z-index: 1300;
font-family: 'MelbourneRegular', Arial, sans-serif;
font-size: 16px;
margin-left: auto;
margin-right: auto;
width: 470px;
}

Let me know if you need more assistance.
