Flexslider - Thumbnails Vertically

Question

I am using a Flexslider for image list, but I wonder if there is the option to list the images of the carousel vertically.

Here's what I need to do:

You can see that if I move the images smaller by the arrow, they must scroll vertically.

However, when using the flex, it lists the smaller images horizontally, following image:

Someone ever needed to do this or have any tips on how I can do for the smaller images stay with two limiter and increase down instead of sideways?

Follow the link script I'm using:

The following code:

vm.flex_interna = function(){
         $('#carousel').flexslider({
            animation: "slide",
            controlNav: false,
            animationLoop: false,
            direction: "vertical",
            slideshow: false,
            itemWidth: 210,
            itemMargin: 5,
            asNavFor: '#slider'
        });
        $('#slider').flexslider({
            animation: "fade",
            controlNav: false,
            animationLoop: false,
            slideshow: false,
            sync: "#carousel"
        });
        }
    vm.flex_interna();

Html:

<div class="flex_conteudo">
