title: Product views datalayer - why does it have a list view?
body: <p>I'm rather confused about why a product view would have a list option. </p>
  
  <p>I feel I'm missing out and sort of want to use it. </p>
  
  <pre><code> 'click': {
      'actionField': {'list': 'Search Results'},      // Optional list property.
  </code></pre>
