title: MVC 4 - Many-to-Many relation and checkboxes
body: <p>I'm working with ASP.NET MVC 4 and Entity Framework. In my database, I have a table <strong>Subscription</strong> which represents a subscription to public transports. This subscription can provide access to several <strong>public transport companies</strong> (so a subscription could have 1, 2, 3, ... companies) then it is a Many-to-Many relation between these tables (I have an intermediate table between them).</p>
  
  <p>I want to allow the creation of a subscription throught a page which will contain a field <em>Amount</em> of the subscription and the available companies by checkboxes. Every checkbox represents an existing company (a company stored in my database).</p>
  
  <p>Any idea about how to do that? I've read this <a href="https://stackoverflow.com/questions/5254893/asp-net-mvc-multiple-checkboxes">ASP.NET MVC Multiple Checkboxes</a> but it was not really helpful.</p>
  
  <p>EDIT : Here is my tables diagram.</p>
