I am currently intergrating Episerver with an API.

Its pretty simple, I post a form from my Episerver website, and the form data gets sent to the API and is processed by some other system.

I have already made a hardcoded HTML form and got the form posting to my API with no problems. - So I have got that bit to work.

Now what I need to do, is create managment functiality for the form it self.....

Requirements

A user can create a form.
One of the fields in the form needs to have a drop downlist with a dyamic list of values (configured in episerver).
The rest of the fields that appear on the form (just strings) are determined by what the user selects from the drop downlist.

(there is a fixed list of fields that could be on the form) I need to store this list somewhere in episerver.

I need for someone to be able to log on to episerver, create a new "API Form Block" enter a list of items for the drop downlist, and then for each item in that list, select from a fixed number of form fields to be assosiatited with that drop down list item.

I appriciate that there are many parts to this question, and I understand I will need to write some front end code to show/hide the correct fields based on the dropdown selection, im not asking for advice about how to do any of that.

The main thing I want suggestions on, is what features of episerver can help me to store the data structure Required, I have started looking at the PopertyList but not to sure if this is the correct approach, how could I assosiate a row in a Propertylist with Sevral rows in another PropertyList? 

This is my first EPI server project, so I'm hoping there might be something I don't know about in episerver which will make this task easy.


Ideas please........? 

UPDATE:

I have started trying to implement this using a Property List. I know how to create a basic property list, but is it possible to have a selection of check boxes in a property list? Something like this:
