At the end of the day, Rails is mostly a server side thing. In any
sensible world your choice of front end tools (javascript libraries
and so on) doesn't impact on the backend (be it rails, a php framework
etc.).
Making a list like that with items from your app doesn't require big
chunks of integration. create the html for the list items as you would
for a completely static display (just ensuring that each element has a
DOM id). Then you need to run the javascript that will setup the
scriptaculous side of things. If you want to do exactly what that
example website does then you might have to generate some javascript
yourself (rails can make the script tags for you but then you need to
fill in the blanks), or if what you want is what the scriptaculous
helpers do then something like
<%= sortable_element 'message_list',
:url => sort_things_path,
:complete=> visual_effect(:highlight, 'message_list'),
:tag => 'div'%>
will do the trick.
