I'm putting together a UI that enables people to search for alternates and
replacement items. The main use case is:
"I have item X - show me if it is valid. If not, show me the alternatives".
Does anyone have any good examples of online (web apps) that deal with this
nicely from a UI perspective?
The trick here, to me, is that the UI needs to clearly show that the
original item (the one the person searched for) is or isn't valid. If it
isn't valid, displaying the alternatives in a clear manner.
There are some other minor constraints that I'm dealing with as well...
