Hello,

I'm working on developing a website that will involve some data forms that need a number of advanced features.  I'm looking for advice on a good Forms module to use to do all or most of the following things:

-Let the user dynamically add new sub-forms to the page while filling out the form.  (There will be a section on the form about activities, for which there will be 5 questions per activity.  I would like the user to be able to click a button to add as many activities as they like and fill out the same 5 questions for each activity they add.)

That's probably the trickiest one, but I also need to be able to do these things:

-Show data from previously submitted forms alongside the data from the current form (forms will be tied to the UserID).

-Allow users to save their progress on a form.

-Have a print feature that loads a decent printable version of the form before or after the form is submitted.

Are there any forms modules that can do all or most of these things?  While the first feature is possibly the trickiest, I can probably settle for setting a max of 10 activities and just pre-program 10 iterations of the sub-form, while perhaps adding something to hide/unhide the extra activity forms.

Thanks in advance!

Joe
