title: How to handle nested forms in ASP.NET MVC
body: <p>I'm trying to build a fairly complex form which as a couple of cascading selects - i.e. the user selects a value in one combo and the other combo is populated according to their first selection. </p>
  
  <p>I've followed a <a href="http://weblogs.asp.net/raduenuca/archive/2011/03/06/asp-net-mvc-cascading-dropdown-lists-tutorial-part-1-defining-the-problem-and-the-context.aspx" rel="nofollow">tutorial</a> on how to handle the cascading but the problem I have is that I now have nested forms (the code in the tutorial uses forms inside partial views to POST to a controller action to load the 2nd combo). I have my main form on which I want to collect the input values but also the nexted forms for the cascading select boxes. The problem I have is that the cascading selection doesn't post to the correct controller action, but instead posts to my main (outer) form's action.</p>
  
  <p>I understand this is the correct behaviour for a browser (as nested forms apparently aren't supported) but what's the correct way to implement this?</p>
