nested-forms

I'm using Rails 2.3.5 and have a nested structure as follows:

Lists has_many Items

Items_Features has_many Features
Items_Features has_many Items

Items_Features has a text field to hold the value of the feature

Then I have a nested form with partials to update and display this so that it updates Lists, Items and Items_Features

What I want to do is generate input fields for each of the rows in features so that the user can fill in a value and it gets inserted/updated in items_features. I also want a label next to the box to display the feature name.

It might look like this:

List name: Cheeses
    Item1 name: Edam
         Feature, hardness: - fill in - <= this list of features from feature table
         Feature, smell: - fill in -

How can I interrupt the nice and easy accepts_nested_attributes_for system to display this as I want?
