3 levels in the navigation menu

Hi,

I hope I’ll be able to translate it correctly.

On the demo Aegaeus, the menu has 3 levels, for example :

PORTFOLIO
. Standard portfolio – Portfolio Gallery – Possibilities
. TWO COLUMNS – THREE COLUMNS – etc…

I need this kind of menu, then the customer will see all the pages in the menu. I don’t know if I’m clear.. It’s hard in english to explain 🙂

But actually, here what I have on my new website :

And I don’t want those > to go to an other level of link…
Please, can you tell me how I can modify the look of my menu ?

Many thank in advance
