title: Capybara writing drop down's options texts into an array
body: <p>I'd like to put a dropdown list's options into an array generically in capybara. After the process I'm expecting to have an arrray of strings, containing all dropdown options. I've tried the code below but the length of my array stays 1 regardless of what the option count is.</p>
  
  <pre><code>periods = Array.new()
  periods = all('#MainContent_dd')
  print periods.length
  </code></pre>
