title: Play 2: How to parse a dynamic list of form inputs in Scala controller?
body: <p>I have a form where the number of input fields is dynamic. </p>
  
  <p>How can these input fields be mapped with a play form? Let's say, the name of each input tag is 'foo_x' where x is an integer that is incremented each time a new input field is dynamically created on the client side. Is there any automatic mapping in Play available or do I have to do this 'by hand' and if so, how can this be done?</p>
