Polymorphic ListField?

[Seth Nickell]

I'd like to create a form that has a list with multiple "types" inside the list. For example, lets say I want a list of "message-posts", but a message post could be a URL field, a text block, or an image. Is there a way to accomplish this with inputEx?

thanks,

I am also interested in Polymorphic ListField. Were you able to make it work?
