title: how to split long symfony form in multiple pages?
body: <p>I want to create a form for an entity which has a many attributes. To ensure the ease of data entry, I want to split that form in multiple pages (for example 2 or 3 pages).
  Let's take the ad entity example:</p>
  
  <ol>
  <li>In page 1, the user will enter the ad text</li>
  <li>In page 2, the user will enter his contact</li>
  <li>In page 3, the user will provide the (X,Y) position of the ad</li>
  </ol>
  
  <p>This split will require saving the available data <em>(inserting in the database)</em> in the 1st page before moving to the next page. Unfortunately, This is not possible due to constraints.</p>
  
  <p>The question is: Is any documentations or any examples that solve this issue?</p>
  
  <p>If no documentation is available, do you think it is better to split my entity in n entities in order to have one entity per page?</p>
  
  <p>Thanks for you help.</p>
