Draggable view with sections

Question

I need a draggable view that includes draggable sections, where both sections and rows are draggable (see image for reference). The sections are not entities on their own. Ideally, the sections would map to a field attached to the entities being output in the view so that they would be available in views, theming, etc. See attached image for reference.

Is there anything in the drupal world that does this today? Looking for ideas or examples on how best to approach this requirement.

Edit Jan 7, 2013 - this is what I have so far, using entity reference, field collection , and field collection table modules, per user user5950's answer below. It's not exactly what I want, and it becomes slow as you add a lot of items (a lot slower to edit a node with 50+ items), but it is functional.

Answer 1

I am using the module Entity reference in conjunction with Field collection to achieve that goal. That means you

1. add a node with an Entity reference field, where you save the rows (if they actually are entities in your case),
2. attach that Entity reference field to a Field collection.
3. Now you can use the delta value of the Entity reference field to sort the row and the delta value of the Field collection field to sort the sections.

Note! You can use core's node edit form as sorting interface. If you would like to have more than one sort you could do that adding a node for each sort. Draggable view becomes useless that way.

Here is an example:

If you want to have an interface, which does not allow to alter other data than the order you could replace the autocomplete field with text an remove the buttons with hook_form_alter().
