html - jQuery: Toggle rotate div on click function

I'm trying to work out if it's possible to toggle the rotation of a div on a click function, e.g. Clicking on a menu button rotates the arrow from pointing downwards to upwards and clicking again will reverse this (upwards to downwards).

I have a jsfiddle demo setup which will make more sense of it: http://jsfiddle.net/bf7Ke/1/
jQuery —

$(document).ready(function(){
        $('.menu-category-title').click(function(){
              $('#menu-'+$(this).attr('hook')).fadeToggle('slow');
              $(this).children('.menu-title-arrow').rotate({animateTo:180});

        return false;
    });
});

Thus far clicking on .menu-category-title fades in the relevant content below and rotates the corresponding arrow by 180 degrees. Clicking .menu-category-title again fades out the relevant content but the arrow stays at 180 degrees. Is there anyway to toggle this function also?
I can't figure it out, any suggestions would be greatly appreciated!

Think you should check if element is visible or not before arrow rotation

$(document).ready(function(){
    $('.menu-category-title').click(function(){
        var elem = $('#menu-'+$(this).attr('hook')),
            arrow = $(this).children('.menu-title-arrow')

        if (!elem.is(':visible'))  {
            arrow.rotate({animateTo:180});
        } else {
            arrow.rotate({animateTo:360});
        }
        elem.fadeToggle('slow', function() {
        });

    return false;
   });
});
