title: How to select a option from drop down using select_list comment in capybara page-object
body: <p>For HTML like this:</p>
  
  <pre><code>&lt;select class="intl_drop" name="select_locale"&gt;
    &lt;option value="0"&gt;- Select One -&lt;/option&gt;
    &lt;option value="1"&gt;United States - English&lt;/option&gt;
    &lt;option value="2"&gt;United States - Español&lt;/option&gt;
    &lt;option value="3"&gt;Canada - English&lt;/option&gt;
  </code></pre>
  
  <p>when I try to select the option using</p>
  
  <pre><code>select_list(:select_lang, :class =&gt; "intl_drop", :index =&gt; 1)
  </code></pre>
  
  <p>I'm getting the error message</p>
  
  <pre><code>Unable to locate element{"method":"xpath","selector":".//select[@class=' intl_drop'][2]"} (Selenium::WebDriver::Error::NoSuchElementError)
  </code></pre>
  
  <p>It works fine when I do not use the index value.</p>
