title: how do i create a auto adaptive form
body: <p>I want to create a dynamic form on my website.</p>
  
  <p>On my site a have several forms that are subject specific but i also have a contact us form with a subject dropdown from which they can choose any of the subjects that the subject specific forms cover.</p>
  
  <p>now if they select website design enquiry i need to ask them for their website address whereas website address isn't relevant to all of the other enquiry subjects, if they ask about website hosting i again need their website address but also need their preference of hosting package.</p>
  
  <p>if they ask about mobile app development i don't need the website or hosting package fields but need 4 checkboxes to appear to allow them to tick the ones relating to the platforms for which the mobile app is to be developed for.</p>
  
  <p>so it needs to be auto adaptive to the type of enquiry selected.</p>
  
  <p>how can i acheive this?</p>
