title: Get complete source code from a website generated on clicking a button
body: <p>The webpage for which I want the source code contains some products.</p>
  
  <p>When I simply load it, it gives me only the source code of the first few products.</p>
  
  <p>What I need is the complete source code after clicking the <kbd>Show 140-250 items</kbd> which is generated several times and get the code when there is no something like <kbd>Show x - y items</kbd> anymore. The <code>id</code> of the button being generated is <code>see-more-products</code>.</p>
  
  <p>I have tried <code>urllib</code>, <code>requests</code> modules, which don't do the job as expected. </p>
  
  <p>Link to that particular page is in comments.</p>
  
  <p>Any help is appreciated. Thanks :)</p>
