title: Some kind of JS conflict in shopify catalog
body: <p>Using a Shopmusic theme as a base.</p>
  
  <p>Trying to have all the products on the main page. When I moved collection.liquid code to index (just the way it was told in tutorial)- javascript stopped working. When you go to collections/all, or any other collection, as a collection- it works perfectly. When i assign a certain collection to a certain page- JS for the product grid stops working on that page.</p>
  
  <p>To be more exact, lightbox doesn't work, umbrella is lagging (when you add a product to a cart, link simply sends you to a cart page instead of simply updating a number)</p>
  
  <p>After searching for a while, i figured, it's most likely some kind of JS conflict. Can't figure out what's in conflict, though.</p>
