title: Add input fields based on condition with Gravity Forms
body: <p>In Gravity Forms, I have a form containing some input fields asking for number of rooms for each room type.</p>
  
  <p>How can I dynamically add input fields for number of each content in the room? Eg if the previous input field was entered as 
  Bedrooms: 2</p>
  
  <p>Then how can I dynamically add a section or table asking for quantity of contents for each room such as:</p>
  
  <p><strong>Bedroom 1</strong>
  <br>Bed (Kind): n
  <br>Bed (Queen): n
  <br>Content N: n...</p>
  
  <p><strong>Bedroom 2</strong>
  <br>Bed (Kind): n
  <br>Bed (Queen): n
  <br>Content N: n...</p>
  
  <p>Is there a advanced field to do this?  I guess I may need to use JS to do this? 
  If so, how can I make sure these fields can be seen in entries? </p>
  
  <p>I'm thinking of using table, but not sure how to with Gravity Forms.</p>
