Can I set two Column in CarouFredSel Slider at a time?

Question

I'm using carouFredSel slider. It's coming out 6 items at a time. I want to set this 3row & 2Column (total 6 items) at a time. How can I set this?

$(window).load(function() {
  $("#main_new_area").carouFredSel({
    auto: 7500,
    width: "variable",
    height: "auto",
    circular: !1,
    scroll: {
      fx: "crossfade",
      duration: 500,
      easing: "linear"
    },
    items: {
      start: 6,
      visible: 6
    },
    pagination: ".new_pager",
    prev: ".new_prev",
    next: ".new_next"
  })
});
