there are 2 sliders
 horizontal one is working fine
 i need to animate the vertical slider like the horizontal animation.
code of the vertical slider is below.
<script type="text/javascript">
(function ($) {    
$.fn.simpleSpy = function (limit, interval) {
  // set some defaults
  limit = limit || 4;
  interval = interval || 4000;
  return this.each(function () {
    // 1. setup
      // capture a cache of all the list items
    var $list = $(this),
      items = [], // uninitialised
      currentItem = limit,
	  currentPage=1;
      total = 0, // initialise later on
      height = $list.find('> li:first').height();
	  singleHeight = $list.find('> li:first').height();
          
    // capture the cache
    $list.find('> li').each(function () {
      items.push('<li>' + $(this).html() + '</li>');
    });
    
    total = items.length;
	pages=Math.ceil(total/limit);
   // alert(Math.ceil(1.2));
    //console.log(total);
	
    // chomp the list down to limit li elements    
    $list.find('> li').filter(':gt(' + (limit - 1) + ')').remove();
//
	function spy(){
// 4. Bind to the forward and back buttons
        $('a.back_cart').click(function () {   
	    return gotoPage(currentPage - 1);          
        });
        
        $('a.next_cart').click(function () {
            return gotoPage(currentPage + 1);
        });
 
  // 5. paging function
        function gotoPage(page) {
			
            var dir = page < currentPage ? -1 : 1, // page < currentPage ? 1 : -1,
                n = Math.abs(currentPage - page),
                top = singleHeight * dir * limit * n;
           // alert($('ul.spy').scrollTop);
            // console.log('currentPage', currentPage, 'left', left, 'n', n);
            
            $('ul.spy').filter(':not(:animated)').animate({
                scrollTop : '+=' + top
            }, 500, function () {
                if (page == 0) {
                    currentPage = pages;
                    // $wrapper.css('scrollLeft', singleWidth * visible * pages); //  * -1
                    this.scrollTop = singleHeight * limit * pages;
					
                } else if (page > pages) {
                    currentPage = 1;
                    this.scrollTop = singleHeight * limit; //  * -1
					
                    // $wrapper.css('scrollLeft', singleWidth * visible); //  * -1
                    // reset back to start position
                } else {
                    currentPage = page;
                }
            });                
            
            return false;
        }
		
		}
		
		
		
		
		
   
    
   spy();
  });
};    
})(jQuery);
</script>

One big mess is here uff....

First of all - here is the code you need, and modyfications in HTML:

Instead of having:


<ul style="padding-left:35px; margin-top:30px; border:1px solid white;" class="spy" >
         <!-- <li>
                      </li>-->
          </ul>

Do some wrappings like:

<div id="dropContent">
<ul style="padding-left:35px; margin-top:30px; border:1px solid white;" class="spy" >
         <!-- <li>
                      </li>-->
          </ul>
</div>


this dropContent should have css styles like:

overflow:hidden
height:200px         (or more as you wish)




then do this:













If it wont work just do those changes and give me link with newest version
$.fn.drag_slider2 = function () {
    function repeat(str, num) {
        return new Array( num + 1 ).join( str );
    }
 
    return this.each(function () {
//console.log(this);
        var $wrapper = $(this),
            $slider = $wrapper.find('>ul'),
            $items = $slider.find('>li'),
            $single = $items.filter(':first'),
 
            singleHeight = $single.outerHeight(), //parseInt($single.width()) + parseInt($single.css('padding-left')) + parseInt($single.css('padding-right')),
            visible = Math.ceil($wrapper.innerHeight() / singleHeight)  ,//  <!--note: doesnt include padding or border-->
 
            currentPage = 1,
            pages = Math.ceil($items.length / visible);
            console.log($single);
//alert($items.length);
        // 1. Pad so that 'visible' number will always be seen, otherwise create empty items
        if (($items.length % visible) != 0) {
            $slider.append(repeat('<li class="empty" />', visible - ($items.length % visible)));
            $items = $slider.find('>li');
        }
 
        // 2. Top and tail the list with 'visible' number of items, top has the last section, and tail has the first
        $items.filter(':first').before($items.slice(- visible).clone().addClass('cloned'));
       $items.filter(':last').after($items.slice(0, visible).clone().addClass('cloned'));
        $items = $slider.find('> li'); // reselect
 
        // 3. Set the left position to the first 'real' item
        // $wrapper.css('scrollLeft', singleHeight * visible); // * -1
        $wrapper.get(0).scrollTop = singleHeight * visible;
 
        // 4. Bind to the forward and back buttons
        $('a.back_cart', this).click(function () {
            return gotoPage(currentPage - 1);
        });
 
        $('a.next_cart', this).click(function () {

                top = singleHeight * dir * visible * n;
