Bagaimana cara membuat menu geser yang mirip dengan menu samping Facebook Mobile dengan html, css, jquery?

//when the trigger is clicked we check to see if the popout is currently hidden
//based on the hidden we choose the correct animation
$('#trigger').click( function() {
    if ($('#popout').hasClass('hidden')) {
        $('#popout').removeClass('hidden');
        showPopout();
    }
    else {
        $('#popout').addClass('hidden');
        hidePopout();
    }
});

function showPopout() {
    $('#popout').animate({
        left: 0
    }, 'slow', function () {
        $('#trigger span').html('Close');  //change the trigger text at end of animation
    });
}

function hidePopout() {
    $('#popout').animate({
        left: -40
    }, 'slow', function () {
        $('#trigger span').html('Show');  //change the trigger text at end of animation
    });
}

/* minimal CSS */
 #popout {
    position: fixed;                /* fix the popout to the left side of the screen */
    top: 50px;
    left: -40px;                    /* use a negative margin to pull the icon area of the popout off the edge of the page */
    width: 75px;
    border: 1px dotted gray;
    color: gray;
}
#trigger {                          /* create a clickable area that triggers the slide in/out effect */
    position: absolute;             /* position clickable area to consume entire right section of popout (add a border if you want to see for yourself) */  
    top: 0;
    bottom: 0;
    right: 0;
    cursor: pointer;   
}

$('#toggle').toggle( 
    function() {
        $('#popout').animate({ left: 0 }, 'slow', function() {
            $('#toggle').html('Close');
        });
    }, 
    function() {
        $('#popout').animate({ left: -40 }, 'slow', function() {
            $('#toggle').html('Show');
        });
    }
