If you are looking to dynamically integrate the URL of the recipe that you want associated with one or more recipes on a page, you can dynamically set the value of the data-recipesifter-url and id attribute to the URL for each of the recipes.

<div id="<Widget Container ID>"
     data-recipesifter-url="<Recipe URL>">
  <script>
    recipeSifterQueue.push(function() {
      recipeSifter.displayButton('<Widget Container ID>');
    })
  </script>
</div>
