title: Marking instead of hiding items with Isotope
body: <p>Is it possible to somehow avoid hiding items while filtering content with (jQuery) Isotope?</p>
  
  <p>The solution I'm after is to keep all elements in their positions in the Isotope container while somehow marking several after clicking on a button - the important thing is to show all the elements in the container all the time.</p>
  
  <p>I'm aware that Isotope offers sorting, but I'm not sure if that's possible with sorting either.</p>
