title: Creating a dynamic one page web application
body: <p>I would like to make a web application (PHP) that will have overlay container that contain dynamic fields/forms.  </p>
  
  <p>I would like the user to complete the form but not be taken away from the main part of the page.  </p>
  
  <p>Imagine, browsing a website and reporting a page error into an overlay but not being taken away from the page you were reading.  </p>
  
  <p>Also, is it possible to make the form multiple parts/pages, such as user clicks next button and the next part of the form is presented? </p>
