title: Multiple Forms in One Form
body: <p>I'm working in ASP.net MVC 5 project.
  I have a parent form that post data to multiple tables in database.
  This parent form has a sub form that goes into another web page that posts its data into another table in database, and gets back to parent form. When user gets back to main form, data that has been entered shouldn't be lost.
  Is that possible? and how through AJAX?</p>
  
  <p>The other sub forms are adding multiple items. The list view of both sub forms should be in the parent form, while the adding input fields should be in modal window. How to implement those too?<a href="https://i.stack.imgur.com/7XeSW.png" rel="nofollow noreferrer">wireframe</a></p>
