How to create multiple row carousel on FlexSlider

I am using flexslider on one of the page I'm working on but got in to problem when the carousel would need to be in two(2) rows. The problem is that there's no available option on flexslider to do it. So, what I did is to do a work around on my own. Please see below of what I did.

First, I set the basic carousel config on flexslider, this is the carousel in one(1) row. Please take note that you need to load the flexslider plugin on your page, you can download it here - http://www.woothemes.com/flexslider/.

$(window).load(function() {
    var itemCnt = 5; // this will be the number of columns per row
    var iWidth = parseFloat($('.flexslider').width() / itemCnt);
    $('.flexslider').flexslider({
        animation: "slide",
        slideshowSpeed: 1000,
        animationSpeed: 300,
        animationLoop: false,
        directionNav: false,
        slideshow: false,
        touch: true,
        itemWidth: iWidth,
        minItems: itemCnt,
        maxItems: itemCnt
    });
});

Next, is to create a function that will create 2 rows from the basic 1 row slider carousel and this will be called on start function of the slider.

function make2Rows(iWidth) {
    var iHeight = parseFloat($('.flexslider .slides > li').height());
    $('.alliance-list .slides > li').css('width', iWidth+'px');
    $('.alliance-list .slides > li:nth-child(even)').css('margin', iHeight+'px 0px 0px -'+iWidth+'px');
}

$(window).load(function() {
    var itemCnt = 5; // this will be the number of columns per row
    var iWidth = parseFloat($('.flexslider').width() / itemCnt);
    $('.flexslider').flexslider({
        animation: "slide",
        slideshowSpeed: 1000,
        animationSpeed: 300,
        animationLoop: false,
        directionNav: false,
        slideshow: false,
        touch: true,
        itemWidth: iWidth,
        minItems: itemCnt,
        maxItems: itemCnt,
        start: make2Rows(iWidth)
    });
});

That's it and hope this would help anyone who are using flexslider as carousel.
