Help with click() and second click

Help with click() and second click

Hello, 

I have my code:

$('.menu .toggle').click(function(){
   $('.menu ul').animate({
      top:0,
   });
   $('.menu ul li').delay(300).fadeIn(500);
});

The animation works great. Now, how can I hide the element?

On second click simply I want to change the css of menu ul into top:-300px.
