I realize this is a prototype but I can't even make sense of the base example shown here: http://www.lightningdesignsystem.com/components/lookups#overview&role=regular&status=all
I assume this should work as a typeahead component that filters the results and allows the user to select one. I can't get the example on their pageto filter or do anything and I'm having the same result when copying the sample HTML into my page.
The example displaying the simulated results for the 'ac' search isn't even displayed the correct filtered results. Am I missing something here or is this prototype not actually usable at this point?
