Thumbnail Grid with Expanding Preview

A tutorial on how to create a thumbnail grid with an expanding image preview similar to the effect seen on Google Images.
Thumbnail Grid with Expanding Preview

From our monthly sponsor: monday.com, a new way to manage your work! Meet the new visual project management tool.

If you have searched images on Google recently, you might have noticed the interesting expanding preview for a larger image when you click on a thumbnail. It’s a really nice effect and it is very practical, making a search much easier. Today we want to show you how to create a similar effect on a thumbnail grid. The idea is to open a preview when clicking on a thumbnail and to show a larger image and some other content like a title, a description and a link.

The interesting part is to calculate the correct preview height and to scroll the page to the right position. We’ll expand the preview in a way so that we can see the respective thumbnail row and cover the rest of the remaining page. Note that we don’t use very large images for the preview in the demo so you might see a lot of empty space on large monitors.

The demo features some amazing artwork by Jaime Martinez.

So let’s start!

The Markup

Initially, we need a thumbnail grid for which we will use an unordered list. Each list item will contain an anchor which will have several data attributes:

<ul id="og-grid" class="og-grid">
	<li>
		<a href="http://cargocollective.com/jaimemartinez/" data-largesrc="images/1.jpg" data-title="Azuki bean" data-description="Swiss chard pumpkin bunya nuts maize plantain aubergine napa cabbage soko coriander sweet pepper water spinach winter purslane shallot tigernut lentil beetroot.">
			<img src="images/thumbs/1.jpg" alt="img01"/>
		</a>
	</li>
	<li>
		<a href="http://cargocollective.com/jaimemartinez/" data-largesrc="images/2.jpg" data-title="Veggies sunt bona vobis" data-description="Komatsuna prairie turnip wattle seed artichoke mustard horseradish taro rutabaga ricebean carrot black-eyed pea turnip greens beetroot yarrow watercress kombu.">
			<img src="images/thumbs/2.jpg" alt="img02"/>
		</a>
	</li>
	<li><!-- ... --></li>
	<!-- ... -->
</ul>

The href value will be used to construct the link in the preview description (this also comes in handy when JavaScript is disabled). The data-largesrc attribute contains the path to the larger image. data-title and data-description contain the title and description, respectively.

When we click on a thumbnail, we want a preview element to appear under the list item. For that we will need to insert an element into the grid. In fact, we will use the list item itself and add the preview element after the anchor:

<li>

	<a href="http://cargocollective.com/jaimemartinez/" data-largesrc="images/2.jpg" data-title="Veggies sunt bona vobis" data-description="Komatsuna prairie turnip wattle seed artichoke mustard horseradish taro rutabaga ricebean carrot black-eyed pea turnip greens beetroot yarrow watercress kombu.">
		<img src="images/thumbs/2.jpg" alt="img02"/>
	</a>
	
	<div class="og-expander">
		<div class="og-expander-inner">
			<span class="og-close"></span>
			<div class="og-fullimg">
				<div class="og-loading"></div>
				<img src="images/2.jpg">
			</div>
			<div class="og-details">
				<h3>Veggies sunt bona vobis</h3>
				<p>Komatsuna prairie turnip wattle seed artichoke mustard horseradish taro rutabaga ricebean carrot black-eyed pea turnip greens beetroot yarrow watercress kombu.</p>
				<a href="http://cargocollective.com/jaimemartinez/">Visit website</a>
			</div>
		</div>
	</div>

</li>

Let’s style everything!

The CSS

Note that the CSS will not contain any vendor prefixes, but you will find them in the files.

So, let’s start with the thumbnail grid. It will be full width and we’ll center the text. In this case this will mean that it will center the thumbnails because we’ll set them to display: inline-block:

.og-grid {
	list-style: none;
	padding: 20px 0;
	margin: 0 auto;
	text-align: center;
	width: 100%;
}

.og-grid li {
	display: inline-block;
	margin: 10px 5px 0 5px;
	vertical-align: top;
	height: 250px;
}

The links and images will be displayed as block elements and we’ll remove some default styling:

.og-grid li > a,
.og-grid li > a img {
	border: none;
	outline: none;
	display: block;
	position: relative;
}

When we click on an item, we will give a special class to the respective list item which will be called og-expanded. We’ll add a little arrow as pseudo-element to the anchor:

.og-grid li.og-expanded > a::after {
	top: auto;
	border: solid transparent;
	content: " ";
	height: 0;
	width: 0;
	position: absolute;
	pointer-events: none;
	border-bottom-color: #ddd;
	border-width: 15px;
	left: 50%;
	margin: -20px 0 0 -15px;
}

The preview itself will have the class og-expander and we’ll position that element absolutely. The initial height of the preview will be 0 and we’ll set the overflow to hidden:

.og-expander {
	position: absolute;
	background: #ddd;
	top: auto;
	left: 0;
	width: 100%;
	margin-top: 10px;
	text-align: left;
	height: 0;
	overflow: hidden;
}

.og-expander-inner {
	padding: 50px 30px;
	height: 100%;
}

The inner division will have some paddings and a height of 100%.

The cross for closing the preview will be created using pseudo-elements, i.e. two rotated lines:

.og-close {
	position: absolute;
	width: 40px;
	height: 40px;
	top: 20px;
	right: 20px;
	cursor: pointer;
}

.og-close::before,
.og-close::after {
	content: '';
	position: absolute;
	width: 100%;
	top: 50%;
	height: 1px;
	background: #888;
	transform: rotate(45deg);
}

.og-close::after {
	transform: rotate(-45deg);
}

.og-close:hover::before,
.og-close:hover::after {
	background: #333;
}

The wrappers for the image and for the details will be 50% wide and we’ll make them float next to each other:

.og-fullimg,
.og-details {
	width: 50%;
	float: left;
	height: 100%;
	overflow: hidden;
	position: relative;
}

The details wrapper will have some padding and we’ll center the image inside of the image wrapper by setting the text-align to center and the image itself to display: inline-block. The image will also have a max-height and max-width of 100% so that it adjusts its size to the surrounding container:

.og-details {
	padding: 0 40px 0 20px;
}

.og-fullimg {
	text-align: center;
}

.og-fullimg img {
	display: inline-block;
	max-height: 100%;
	max-width: 100%;
}

Let’s style the text elements and the link:

.og-details h3 {
	font-weight: 300;
	font-size: 52px;
	padding: 40px 0 10px;
	margin-bottom: 10px;
}

.og-details p {
	font-weight: 400;
	font-size: 16px;
	line-height: 22px;
	color: #999;
}

.og-details a {
	font-weight: 700;
	font-size: 16px;
	color: #333;
	text-transform: uppercase;
	letter-spacing: 2px;
	padding: 10px 20px;
	border: 3px solid #333;
	display: inline-block;
	margin: 30px 0 0;
	outline: none;
}

.og-details a::before {
	content: '2192';
	display: inline-block;
	margin-right: 10px;
}

.og-details a:hover {
	border-color: #999;
	color: #999;
}

The loading element will be in the same container as the image and we’ll not use any images but this CSS-only technique. We’ll create a little circle and set three box shadows: one for making the circle itself look a bit smoother and two for “copying” the element. Then we create an animation that will change the background color and the box shadow colors sequentially:

.og-loading {
	width: 20px;
	height: 20px;
	border-radius: 50%;
	background: #ddd;
	box-shadow: 0 0 1px #ccc, 15px 30px 1px #ccc, -15px 30px 1px #ccc;
	position: absolute;
	top: 50%;
	left: 50%;
	margin: -25px 0 0 -25px;
	animation: loader 0.5s infinite ease-in-out both;
}

@keyframes loader {
	0% { background: #ddd; }
	33% { background: #ccc; box-shadow: 0 0 1px #ccc, 15px 30px 1px #ccc, -15px 30px 1px #ddd; }
	66% { background: #ccc; box-shadow: 0 0 1px #ccc, 15px 30px 1px #ddd, -15px 30px 1px #ccc; }
}

Last, but not least, we’ll add two media queries for adjusting the text a bit and for hiding the full image once the screen gets so small that the preview image is not really useful anymore (we’ll also not load it in the JavaScript then).


@media screen and (max-width: 830px) {

	.og-expander h3 { font-size: 32px; }
	.og-expander p { font-size: 13px; }
	.og-expander a { font-size: 12px; }

}

@media screen and (max-width: 650px) {

	.og-fullimg { display: none; }
	.og-details { float: none; width: 100%; }
	
}

That’s all the style. Now, let’s take a look at the JavaScript.

The JavaScript

Let’s start by caching some elements and initializing some variables:

	// list of items
var $grid = $( '#og-grid' ),
	// the items
	$items = $grid.children( 'li' ),
	// current expanded item´s index
	current = -1,
	// position (top) of the expanded item
	// used to know if the preview will expand in a different row
	previewPos = -1,
	// extra amount of pixels to scroll the window
	scrollExtra = 0,
	// extra margin when expanded (between the preview element and the next item row)
	marginExpanded = 10,
	$window = $( window ), winsize,
	$body = $( 'html, body' ),
	// transitionend events
	transEndEventNames = {
		'WebkitTransition' : 'webkitTransitionEnd',
		'MozTransition' : 'transitionend',
		'OTransition' : 'oTransitionEnd',
		'msTransition' : 'MSTransitionEnd',
		'transition' : 'transitionend'
	},
	transEndEventName = transEndEventNames[ Modernizr.prefixed( 'transition' ) ],
	// support for csstransitions
	support = Modernizr.csstransitions,
	// default settings
	settings = {
		minHeight : 500,
		speed : 350,
		easing : 'ease'
	};

We will start by preloading all the images (thumbnails) in the grid. We then save the offset top and height for each item in the grid, get the current window’s size, and initialize some events:

	function init( config ) {
		
		// the settings..
		settings = $.extend( true, {}, settings, config );

		// preload all images
		$grid.imagesLoaded( function() {

			// save item´s size and offset
			saveItemInfo( true );
			// get window´s size
			getWinSize();
			// initialize some events
			initEvents();

		} );

	}

	// saves the item´s offset top and height (if saveheight is true)
	function saveItemInfo( saveheight ) {
		$items.each( function() {
			var $item = $( this );
			$item.data( 'offsetTop', $item.offset().top );
			if( saveheight ) {
				$item.data( 'height', $item.height() );
			}
		} );
	}

	function getWinSize() {
		winsize = { width : $window.width(), height : $window.height() };
	}

We will bind the click event for each item (anchor) and for the close button (when the item is opened). When we click on an item, the preview with the large image source and the details will be revealed or hidden if already shown. If we click the close button (cross) on the preview then this preview will be closed too.
We are also binding the resize event for the window, where some values are reset and the preview gets closed (if opened).

	function initEvents() {
		
		// when clicking an item, show the preview with the item´s info and large image;
		// close the item if already expanded.
		// also close if clicking on the item´s cross
		$items.on( 'click', 'span.og-close', function() {
			hidePreview();
			return false;
		} ).children( 'a' ).on( 'click', function(e) {

			var $item = $( this ).parent();
			// check if item already opened
			current === $item.index() ? hidePreview() : showPreview( $item );
			return false;

		} );

		// on window resize get the window´s size again
		// reset some values..
		$window.on( 'debouncedresize', function() {
			
			scrollExtra = 0;
			previewPos = -1;
			// save item´s offset
			saveItemInfo();
			getWinSize();
			var preview = $.data( this, 'preview' );
			if( typeof preview != 'undefined' ) {
				hidePreview();
			}

		} );

	}

With the showPreview function we will basically initialize the Preview object, which in turn will expand and reveal the details and the large version of the image. If a Preview instance is already initialized then we will only update the preview with the new details (if the clicked item is in the same row as the current expanded item) or hide it and initialize / open a new one (if not in the same row).
In order to check if the items are in the same row as the current preview, we use the offset top value of the items.

	function showPreview( $item ) {

		var preview = $.data( this, 'preview' ),
			// item´s offset top
			position = $item.data( 'offsetTop' );

		scrollExtra = 0;

		// if a preview exists and previewPos is different (different row) from item´s top, then close it
		if( typeof preview != 'undefined' ) {

			// not in the same row
			if( previewPos !== position ) {
				// if position > previewPos then we need to take the current preview´s height in consideration when scrolling the window
				if( position > previewPos ) {
					scrollExtra = preview.height;
				}
				hidePreview();
			}
			// same row
			else {
				preview.update( $item );
				return false;
			}
			
		}

		// update previewPos
		previewPos = position;
		// initialize new preview for the clicked item
		preview = $.data( this, 'preview', new Preview( $item ) );
		// expand preview overlay
		preview.open();

	}

The Preview object will have a reference to the currently displayed item (Preview.$item), and the index of the expanded item (Preview.expandedIdx). Note that the expanded item is not necessarily the displayed item. For instance if we click on a second item that is on the same row as the one clicked before then the Preview will be “reused” and the Preview.expandedIdx will not be the index of the Preview.$item. We need to keep the reference to the expanded item so that when the Preview is closed we know which item to “collapse”.

	// the preview obj / overlay
	function Preview( $item ) {
		this.$item = $item;
		this.expandedIdx = this.$item.index();
		this.create();
		this.update();
	}

As the Preview object is initialized we create the necessary structure where the item´s details will be rendered and we append it to the item:

	create : function() {
		// create Preview structure:
		this.$title = $( '<h3></h3>' );
		this.$description = $( '<p></p>' );
		this.$href = $( '<a href="#">Visit website</a>' );
		this.$details = $( '<div class="og-details"></div>' ).append( this.$title, this.$description, this.$href );
		this.$loading = $( '<div class="og-loading"></div>' );
		this.$fullimage = $( '<div class="og-fullimg"></div>' ).append( this.$loading );
		this.$closePreview = $( '<span class="og-close"></span>' );
		this.$previewInner = $( '<div class="og-expander-inner"></div>' ).append( this.$closePreview, this.$fullimage, this.$details );
		this.$previewEl = $( '<div class="og-expander"></div>' ).append( this.$previewInner );
		// append preview element to the item
		this.$item.append( this.getEl() );
		// set the transitions for the preview and the item
		if( support ) {
			this.setTransition();
		}
	}

Then we fill the previous structure with the item´s details (stored in data attributes and the href).
The update function will also be used to just update the content of an existing preview.

	update : function( $item ) {

		// update with new item´s details 
		if( $item ) {
			this.$item = $item;
		}
		
		// if already expanded, remove class "og-expanded" from current item and add it to new item
		if( current !== -1 ) {
			var $currentItem = $items.eq( current );
			$currentItem.removeClass( 'og-expanded' );
			this.$item.addClass( 'og-expanded' );
			// position the preview correctly
			this.positionPreview();
		}

		// update current value
		current = this.$item.index();

		// update preview´s content
		var $itemEl = this.$item.children( 'a' ),
			eldata = {
				href : $itemEl.attr( 'href' ),
				largesrc : $itemEl.data( 'largesrc' ),
				title : $itemEl.data( 'title' ),
				description : $itemEl.data( 'description' )
			};

		this.$title.html( eldata.title );
		this.$description.html( eldata.description );
		this.$href.attr( 'href', eldata.href );

		var self = this;
		
		// remove the current image in the preview
		if( typeof self.$largeImg != 'undefined' ) {
			self.$largeImg.remove();
		}

		// preload large image and add it to the preview
		// for smaller screens we don´t display the large image (the last media query will hide the wrapper of the image)
		if( self.$fullimage.is( ':visible' ) ) {
			this.$loading.show();
			$( '<img/>' ).load( function() {
				self.$loading.hide();
				self.$largeImg = $( this ).fadeIn( 350 );
				self.$fullimage.append( self.$largeImg );
			} ).attr( 'src', eldata.largesrc );	
		}

	}

To reveal the preview we need to set the height of the Preview element and also of the item (to push down the items below). The height of the preview will be the window´s height minus the height of the grid item. To avoid cases where that height could be too small we add the option “minHeight” where we can specify the minimum height needed for the preview element.
As the preview opens we will want to scroll the window so that the preview is completely visible (and if possible, also the item).

	open : function() {

		setTimeout( $.proxy( function() {	
			// set the height for the preview and the item
			this.setHeights();
			// scroll to position the preview in the right place
			this.positionPreview();
		}, this ), 25 );

	}

	setHeights : function() {

		var self = this,
			onEndFn = function() {
				if( support ) {
					self.$item.off( transEndEventName );
				}
				self.$item.addClass( 'og-expanded' );
			};

		this.calcHeight();
		this.$previewEl.css( 'height', this.height );
		this.$item.css( 'height', this.itemHeight ).on( transEndEventName, onEndFn );

		if( !support ) {
			onEndFn.call();
		}

	}

	calcHeight : function() {

		var heightPreview = winsize.height - this.$item.data( 'height' ) - marginExpanded,
			itemHeight = winsize.height;

		if( heightPreview < settings.minHeight ) {
			heightPreview = settings.minHeight;
			itemHeight = settings.minHeight + this.$item.data( 'height' ) + marginExpanded;
		}

		this.height = heightPreview;
		this.itemHeight = itemHeight;

	}

	positionPreview : function() {

		// scroll page
		// case 1 : preview height + item height fits in window´s height
		// case 2 : preview height + item height does not fit in window´s height and preview height is smaller than window´s height
		// case 3 : preview height + item height does not fit in window´s height and preview height is bigger than window´s height
		var position = this.$item.data( 'offsetTop' ),
			previewOffsetT = this.$previewEl.offset().top - scrollExtra,
			scrollVal = this.height + this.$item.data( 'height' ) + marginExpanded <= winsize.height ? position : this.height < winsize.height ? previewOffsetT - ( winsize.height - this.height ) : previewOffsetT;
		
		$body.animate( { scrollTop : scrollVal }, settings.speed );

	}

When closing the preview we reset the heights of the preview element and the expanded item. Once this is done, the preview element / structure gets removed from the DOM.

	close : function() {

		var self = this,
			onEndFn = function() {
				if( support ) {
					$( this ).off( transEndEventName );
				}
				self.$item.removeClass( 'og-expanded' );
				self.$previewEl.remove();
			};

		setTimeout( $.proxy( function() {

			if( typeof this.$largeImg !== 'undefined' ) {
				this.$largeImg.fadeOut( 'fast' );
			}
			this.$previewEl.css( 'height', 0 );
			// the current expanded item (might be different from this.$item)
			var $expandedItem = $items.eq( this.expandedIdx );
			$expandedItem.css( 'height', $expandedItem.data( 'height' ) ).on( transEndEventName, onEndFn );

			if( !support ) {
				onEndFn.call();
			}

		}, this ), 25 );
		
		return false;

	}

And that's it! We hope you enjoyed this tutorial and find it inspiring!

    Is there a way to include multiple thumbnail grids on a single page? When I try to do so, only the first thumbnail grids maintain functionality; the rest remain static when the thumbnails are clicked and only function as basic image links.

    how do i custom “VISIT WEBSITE” text into several different texts?,,
    because actually i want to include the web title, so the link would be VISIT ‘WEB TITLE’ , something like VISIT CODROPS..

    • 18

      Hi sipo,

      It’s easy to change “VISIT WEBSITE” to something else in the .js file, but you can’t have different labels for different items in the grid. So I just use “MORE” and let the user find out where it goes to when they click.

    Hi guys.

    Good one.

    Only one question. Could you give me some light in why my data-title and data-description are not showing up? Everything else is okay, but only those two have issue.

    Cheers.

    • 25

      In the default.css file have some styles need to use for title & description not showing issues.

      *,
      *:after,
      *:before {
      -webkit-box-sizing: border-box;
      -moz-box-sizing: border-box;
      box-sizing: border-box;
      padding: 0;
      margin: 0;
      }

    Excellent grid Mary Lou, apart for just that one thing about IE8, and – worse yet – the iPad! :/

    I’ve tried playing around with it here: Betty test and everything looked good…until I tried on IE8, and on the iPad.
    It looks nice and and the expander opens fine, but closes automatically again, almost immediately…

    I tried to test the demo posted here as well in IE8 and on the iPad, with the same result, so it doesn’t look like the problem is in my code (for once :))

    If anyone could help, I’d appreciate it greatly, cause I really like the grid!

      Thanks a million, Kent – you’re a life saver 🙂

      I completely missed that other post, but updated the grid.js with debounced instead of throttled, and it did the trick – even in IE7!

      And again multiple thanks to Mary Lou for yet another excellent job here on Codrops 😉

      Did it for me with the GitHub code.
      Expander on an iPod Touch stays ‘expanded’ now. Nice.

      I just need a responsive setup on the ‘examples’ pages.

      Great tutorial. I have used it in one of my websites. But I am having a issue when closing the expanded space. I get a massive white space between each row. I have tried the code suggested above (GitHub) and still doesn’t work. It doesn’t work in Chrome or firefox, so it isn’t just IE.

      Help would be much appreciated 🙂

    Hi!

    Amazing script. Is there a way to add an HREF to the fullimage? I’ve been scratching my head. I’d like the large image to link out to a URL. Only one URL, so I can hardcode it to work for all fullimages.

    much thanks!

    Nice formatting there 🙂
    There should of course have been an A HREF tag surrounding the default DIV inside the ( ” )

    Anyways, hope you get the point…and that it works 🙂

    Hi Manoela, as always Codrops produces detail oriented functional UI / UX concepts, this grid layout is really very helpful in combination with sorting categories or multiple grid blocks on a page or a full-width-responsive-slider maybe.
    Would definitely like to try fusion with royalslider script.

    Thanks for sharing a beautiful code and brilliant mind!

    How can I add HREF’s to the fullimages in HTML?
    I’d like the large images to link out to different URLs (vimeo videos).

    I’ve disable the href in HTML :
    – Put href =”#”

    And changed the grid.js, around line 365,
    – From this:
    this.$title.html( eldata.title );
    this.$description.html( eldata.description );
    this.$href.attr( ‘href’, eldata.href );

    – To this :
    this.$title.html( eldata.title );
    this.$description.html( eldata.description );

    if(eldata.href == ‘#’)
    {
    this.$href.hide();
    }
    else
    {
    this.$href.show();
    this.$href.attr( ‘href’, eldata.href );
    }

    Now, how should I modify the HTML to create links from the fullimages?

      ops, I just saw this post now.
      I am looking for the same thing – sorry for the duplicate post beneath :/

      also tried the anchor, didn’t work.

    I would love to be able to use this as a sell item layout but I can’t figure out how to incorporate a paypal button where the “Visit Website” link is located?

    Question : I am considering added this plug-in to my website.
    Curious, anyone knows how to alter the code to allow for full sized images? I see a lot of people are wondering as well. Potentially being able to integrate fancybox or lightbox with the code?

    If anyone is successful, this would be greatly appreciated,
    Cheers

    Hi! Nicely done! super cool tutorial.

    Here’s one for you:

    – any idea how to share a link with the opened preview?
    the difference in my code is that I don’t need external href for the <a> so I tried using a basic anchor, surely that doesn’t work.
    I see google can do it, so we can do it too 🙂

    anyways, nice work! thanks for sharing this!

    I absolutely love this design and have spent some time adapting it for use in my online coaching practice. For example: http://gusgriffin.net/grid/index.html

    I’ve only been testing the webpage in the current version of Google Chrome so far – I know it has problems with other browsers – swf logo not displaying is one – but I’ll address those later. Fortunately, in my business, I can require a client to use a particular browser if necessary. :o)

    As you can see, even though you can’t use HTML on the text in the expander, you can still do quite a bit of text formatting just using and HTML entities (symbols) rather than tags.

    Can anyone suggest how to separate the VISIT WEBSITE button (in my example, I’ve renamed it MORE) so it can be moved out of the ‘og-details’ area? I’d like to move it to the left below a reduced ‘og-fullimg’ area, so I have more room for text in the ‘og-details’ area.

    Also does anyone know how to make the expander scrollable – specifically give the ‘og-details’ area a scroll-bar (but only if needed) – so that more text can be fitted in as necessary?

    All the best, Gus

    Has anyone tried to get this to work via ajax?? been trying for good couple of weeks just cant seem to get it to play ball 🙁 if anyone has ideas that would be so good.

      We’re having this same issue. We’re wanting to load an Ajax page into the expanded area when the thumbnail is clicked. Our content is being generated dynamically, and there’s a lot of it… so we’re definitely needing there to be an external page. We figured out how to load the ajax page inside of the expander, but the only way that we’ve been able to get this to work is by clearing out all of the other elements from the original expander. Which isn’t ideal because it wipes out the close button.

      Cmdv… I’m not sure if this helps, but we commented out everything from here…
      Preview.prototype = {
      create : function() {

      down to hear…
      if( support ) {

      and then added in this to get a page loading with ajax. (This was put in between the two pieces of code listed above.)
      this.$previewEl = $( ” );
      this.$previewEl.load(‘page_name.html’);
      this.$item.append( this.getEl() );

      If you figure out the rest, after the ajax has been loaded, would you please post about it! Thanks!!

      Hi..Does any one found out how? I came out with this script but doesnt work..


      Preview.prototype = {
      create : function() {
      // create Preview structure:

      var post_url = $(this).attr("href");
      var post_id = $(this).attr("rel");
      this.$loading = $( '<div class="loading">Loading...</div>' );
      this.$previewEl = $( '<div class="og-expander"></div>' ).append( this.$loading );
      this.$previewEl.load('post_url');
      this.$item.append( this.getEl() );
      // set the transitions for the preview and the item
      if( support ) {
      this.setTransition();
      }
      },
      update : function( $item ) {

      if( $item ) {
      this.$item = $item;
      }

      // if already expanded remove class "og-expanded" from current item and add it to new item
      if( current !== -1 ) {
      var $currentItem = $items.eq( current );
      $currentItem.removeClass( 'og-expanded' );
      this.$item.addClass( 'og-expanded' );
      // position the preview correctly
      this.positionPreview();
      }

      // update current value
      current = this.$item.index();

      // update preview´s content
      var $itemEl = this.$item.children( 'a' ),
      eldata = {
      href : $itemEl.attr( 'href' ),
      rel : $itemEl.attr( 'rel' ),
      };

      this.$href.attr( 'href', eldata.href );
      this.$rel.attr( 'rel', eldata.rel );

      var self = this;

      },
