Jquery Superfish menu - How to slide up?

Question

This is the jquery code for superfish menu plugin (after some revisions of mine). I'm looking to add an effect (either through superfish or adventitiously) that would cause the submenus to slide up on mouseout (just as they slide down when you hover a menu-top).

jQuery("ul.sf-menu").supersubs({ 
        minWidth:    12,                                // minimum width of sub-menus in em units 
        maxWidth:    27,                                // maximum width of sub-menus in em units 
        extraWidth:  1                                  // extra width can ensure lines don't sometimes turn over 
                                                        // due to slight rounding differences and font-family 
    }).superfish({ 
        delay:       700,                               // delay on mouseout 
        animation:   {opacity:'show',height:'show'},    // fade-in and slide-down animation 
        speed:       'fast',                            // faster animation speed 
        autoArrows:  true,                             // disable generation of arrow mark-up 
        dropShadows: false                             // disable drop shadows
    });
