title: Include a loop in a loop in Robot Framework
body: <p>I've got a problem with using a loop in another existing loop in RF 
  That is just an example of what I need: I have a list of people (@{people}) and each of the people has a list of items. </p>
  
  <p>I do the following: </p>
  
  <pre><code>:FOR | ${person} | IN @{people} 
  \ | @{items}= | Create List | xpath=//div[@class='item'] 
  \ | :FOR ${item} | IN @{items} 
  \ | \ | ...
  </code></pre>
  
  <p>The problem is on the second :FOR I got an error 'keyword :FOR is not found'. Do I do something wrong? Or is there any other way to include a loop in another loop? </p>
