title: Scraping dynamic content using python-Scrapy
body: <p>Disclaimer: I've seen numerous other similar posts on StackOverflow and tried to do it the same way but was they don't seem to work on this website.</p>
  
  <p>I'm using Python-Scrapy for getting data from koovs.com. </p>
  
  <p>However, I'm not able to get the product size, which is dynamically generated. Specifically, if someone could guide me a little on getting the 'Not available' size tag from the drop-down menu on <a href="http://www.koovs.com/only-onlall-stripe-ls-shirt-59554.html?from=category-651&amp;skuid=236376">this</a> link, I'd be grateful. </p>
  
  <p>I am able to get the size list statically, but doing that I only get the list of sizes but not which of them are available.</p>
