Removed box shadow from dropdowns
Wired up filter panel
Added a dirty hack to pull value from custom column

.. solves an edge case where you want to get ID based on some other
columns, for instance, get id of sw.event document type whose NodeAlias
is 'amazing-event'. This scenario can be solved as
Eval("FieldThatReturnsNodeAlias").GetValueFrom("SW.Event", "EventID",
"NodeAlias")

clear as mud
Translating query parameters to ids

half way there
Added a sample transformation layout for testing
