This sample
nav_controls.jsp file is used for the Relationship
Discovery UI.
The following
nav_controls.jsp file has been modified to display
refinements from the Terms Discovery dimension. Added or modified code is
highlighted in bold face.
<%----------------------------------------------------------------------
DESCRIPTION:
This module displays basic, standard navigation controls. It
is mainly used for debugging purposes and as a starting point for
no-frills navigation solutions. It only displays refinement dimensions,
so this module should be used in conjunction with nav_breadcrumbs.
