should i use javascript or flash for the website menu?

Hi,
I need to design the menu of my website, but the one I currently put is very bad in graphics. I found a website that has exactly the menu I'm trying to do (this one http://leonardo.it/). As you can easily see, there is a black bar on the top of the page, and there are menu entries on it, when you hover the mouse on one of them, under the black bar there is a colored rectangle with the submenu items. They did this in flash, but since I have never used flash, is there a way to do this in javascript? with the onHover function... or, if it's not too difficult I can try with flash, if you can give me some tips.
Thanks,
Marwan

PS. by the way, what do you think about the logo? i'm not too convinced on the design.. I did it with Adobe Illustrator using some simple shapes.
Bye Bye and thanks again!!

The example you provided IS NOT built in flash. Its actually reasonably simple javascript. I think since you don't have any experience with Flash javascript would be a better route to follow (Flash has a pretty steep learning curve at the beginning)

This should be enough to get you started with a jquery menu.

thanks, i'm working on it now!
about the logo? what do you think?

Not sure what logo your talking about.

the logo on the site with the js menu? you didnt give us a link to your site.

the logo is very creative and you could tune it up a little

thanks,
how should I tune it up? (by the way, I put my website both in my user and my signature, so if anyone missed it it's http://www.xday.it)
oh and it's written in italian, as it is aimed at the italian public


thanks to everybody!!!
