vertical vertion

Hi, Ahmed. Tell me please, how i can change on a vertical vertion. In my js file i rewrite your js code, but don-t work correctly.

function createSlider( current ) {
$(‘.woo-variation-product-gallery’).slick( {
vertical : true,
dots : true,
verticalSwiping : true,
arrows : false,
initialSlide: current,
responsive: [{
breakpoint: 768,
settings: {
vertical:false,
verticalSwiping:false,
swipe: true,
draggable: true,
arrows: false
}
}]
});
};
createSlider(0);
