Hello Guys,

I am about to implement an webmail system to one of my clients,
one feature under which is managing the mails, by creating Folders but my clients want to implement in the form Multi_level Folders similar to Eudora or
OE, but since this are windows based applications it easy to manage these stuff over there i.e Managing the Folders by just right clicking the Folders , but i feel this would be impossible in an web based application and also since i am doing it in PHP.

Any suggestions to implement the concept of Multi-Level Folder similar to that of Eudora or Outlook Express as an web based application
