Show Column Configuration Area
Click the Column Configuration icon 
to show the Column Configuration Area. This button only appears if the zone has been configured to
allow columns to be dragged and dropped into the Results Area.
Note: If the zone is configured to have filters and the drag and drop
(column configuration) area, only one or the other is shown at any
given time. It means that a user can either change the filter criteria
and refresh the search results or change the column configuration
and refresh the results.
