-As cool as Isotope is, the only thing that could make it even cooler would be adding bookmark-able URL hashes. Ben Alman's [jQuery BBQ](http://benalman.com/projects/jquery-bbq-plugin/) allows us to do just that.
-
-> jQuery BBQ leverages the HTML5 hashchange event to allow simple, yet powerful bookmarkable #hash history.
-
-[**See Demo: Hash history**](../demos/hash-history.html)
-
-BBQ is a marvelous plugin that provides for a lot more functionality. The [hash history demo](../demos/hash-history.html) uses multiple options (`sortBy`, `sortAscending`, and `layoutMode` in addition to `filter`), the ability to use back-button history, and properly highlights selected links.
-
-Given BBQ's tremendous capabilities, the code can grow to be a bit complex. Be sure to read through [BBQ's docs](http://benalman.com/code/projects/jquery-bbq/docs/files/jquery-ba-bbq-js.html) and take look at [its examples](http://benalman.com/code/projects/jquery-bbq/examples/) before you dive in and code up your own solution.
-
-## Markup
-
-Instead of setting the option values and keys with `data` attributes, we can add the option in the `href` for each link.
-
-{% highlight html %}
-
-<ul class="option-set">
- <li><a href="#filter=*" class="selected">show all</a></li>
- <li><a href="#filter=.metal">metal</a></li>
- <li><a href="#filter=.transition">transition</a></li>
- <li><a href="#filter=.alkali%2C+.alkaline-earth">alkali and alkaline-earth</a></li>
- <li><a href="#filter=%3Anot(.transition)">not transition</a></li>
- <li><a href="#filter=.metal%3Anot(.transition)">metal but not transition</a></li>
-</ul>
-
-{% endhighlight %}
-
-The `href` value is a serialized string, suitable for a URL. These values can be created with [jQuery.param()](http://api.jquery.com/jQuery.param/).
-
-{% highlight javascript %}
-
-$.param({ filter: '.metal' })
-// >> "filter=.metal"
-$.param({ filter: '.alkali, alkaline-earth' })
-// >> "filter=.alkali%2C+alkaline-earth"
-$.param({ filter: ':not(.transition)' })
-// >> "#filter=%3Anot(.transition)"
-
-{% endhighlight %}
-
-## jQuery script
-
-These serialized `href` values can be converted into their proper jQuery object form when clicked using [jQuery.deparam()](http://benalman.com/code/projects/jquery-bbq/docs/files/jquery-ba-bbq-js.html#jQuery.deparam) from jQuery BBQ.
-
-{% highlight javascript %}
-
-$('.option-set a').click(function(){
- // get href attr, remove leading #
- var href = $(this).attr('href').replace( /^#/, '' ),
- // convert href into object
- // i.e. 'filter=.inner-transition' -> { filter: '.inner-transition' }
- option = $.deparam( href, true );
- // set hash, triggers hashchange on window
- $.bbq.pushState( option );
- return false;
-});
-
-{% endhighlight %}
-
-Calling [$.bbq.pushState()](http://benalman.com/code/projects/jquery-bbq/docs/files/jquery-ba-bbq-js.html#jQuery.bbq.pushState) will trigger the `hashchange` event. At that point, we can parse the hash from the URL and use it to trigger the proper change in the Isotope instance.
-
-{% highlight javascript %}
-
-$(window).bind( 'hashchange', function( event ){
- // get options object from hash
- var hashOptions = $.deparam.fragment();
- // apply options from hash
- $container.isotope( hashOptions );
-})
- // trigger hashchange to capture any hash data on init
- .trigger('hashchange');
-
-{% endhighlight %}
-
-Now any filter buttons that are clicked will update the URL hash, so these options can be bookmarked.
