I'm using this fantastic   FILTERABLE PORTFOLIO:  http://webdesigntunes.com/tutorial/filterable/

But now i´am trying to configure the standard filter All (*) with the exception of one category. 

I have these categories:

1.  <nav class="primary clearfix">
                       <ul class="conteudo_corrente">
                         <li><a href="#" class="selected" data-filter="*">All</a></li>
                         <li><a href="#" data-filter=".product">PRODUCT</a></li>
                         <li><a href="#" data-filter=".packaging">GRAPHIC</a></li>
                         <li><a href="#" data-filter=".identity">WEB</a></li>
                         <li><a href="#" data-filter=".others">OTHERS</a></li>
    </ul>
                   </nav>

I'm searching for something that exclude the OTHERS category (do not show up on ALL category) only when i click in OTHERS it show the projects.

A think it is in here:

2. <script>
3. //Portfolio
4. var $container = $('.portfolio');
5. $container.isotope({
6. filter: '*',
7. animationOptions: {
8. duration: 750,
9. easing: 'linear',
10. queue: false,
11. }
12. });
13. 
    
14. $('nav.primary ul a').click(function(){
15. var selector = $(this).attr('data-filter');
16. $container.isotope({
17. filter: selector,
18. animationOptions: {
19. duration: 750,
20. easing: 'linear',
21. queue: false,
22. }
23. });
24.  return false;
25. });
26. 
    
27. var $optionSets = $('nav.primary ul'),
28.       $optionLinks = $optionSets.find('a');
29.  
30.       $optionLinks.click(function(){
31.          var $this = $(this);
32.  // don't proceed if already selected
33.  if ( $this.hasClass('selected') ) {
34.      return false;
35.  }
36.   var $optionSet = $this.parents('nav.primary ul');
37.   $optionSet.find('.selected').removeClass('selected');
38.   $this.addClass('selected'); 
39. });
40. </script>

Any ideas?

Thank you
