jQuery slick carousel "slide" setting
I had similar issue and could solve using following method:
$(".slickContainer").slick({
slide: 'div',
rows: 0
});
I had a similar issue. The trick was, instantiate the slider, then filter out what you WANT to display.
Working Fiddle: https://jsfiddle.net/m8uxqrt3/
$(".slickContainer").slick().slick('slickFilter', '.slickItem');
