jQuery Hover Drop-Down-Menu Full Width Size

jQuery Hover Drop-Down-Menu Full Width Size

I have a vertical menu in my Website. Now i need a dropdown system in some links.
I've see this example on the internet: http://jsfiddle.net/4jxph/3018/ But i want a full width submenu. The Dropdown System of Sony is what I want. Dropdown system by Sony: Sony I've always craetet a full width size dropdown menu.
My Code: http://jsfiddle.net/3aK9k/4/
So what i want, when i hover the content so the submenu and again to the menu link which slidedown the submenu than the submenu should be still there without the slideDown animation.




I hope I've explain what i want to do. I think it is possible but that overwhelmed my knowledge of JS and jQuery.
