title: How to use jQuery selector to filter jQuery isotope items case-insensitive (search)
body: <p>I'm playing around with <a href="http://isotope.metafizzy.co/" rel="nofollow">jQuery Isotope</a> and want to implement an element search.  When the user types into a text box, I change the filter option like this:</p>
  
  <pre><code>var newFilter = '[data-myAttr*="' + $('#mySearchBox').val() + '"]';
  $('#myIsotopeContainer').isotope({filter: newFilter});
  </code></pre>
  
  <p>I'm using jQuery's <a href="http://api.jquery.com/attribute-contains-selector/" rel="nofollow">attribute contains selector</a>.  But it's case-sensitive, and I want to be case-<i>in</i>sensitive.  How can I accomplish this?</p>
  
  <p>I've looked at other questions and Google results that suggest using <code>.filter(fn)</code>, but I don't have that much control with isotope.  I just give it a selector.</p>
