Javascript Help

I need some help doing this page.

I'm trying to do a navigation bar, where when the user clicks one of the items, it expands with a menu, (there are 4 items that expand 4 different menus). I also need a link to show and hide all the menus. Something like this

So anyone have an idea how to do this with javascript?

if ( menu item clicked ) {
    if (menu closed) {
      expand menu
    }
    if (menu opened) {
      close menu
    }
}

if ( link expand clicked ) {
   set all lists to display:block;
}

if ( link collapse clicked ) {
   set all lists to display: none;
}

Just the basic idea, here is the page I'm doing.

www.vastyles.com/new/nav.html

Any help would be appreciated.

Ugh, nevermind lads, I figure it out on my own, so simple I overlooked it.
