This example site shows an end-to-end example of the Widget UI embedded in a bookmaker page. The blue section at the top represents the Bookmaker web site and bet slip. The white section is the Widget UI siting within its iFrame.

See the site.js file for an example of a listener that bubbles up the feedback message described in point 6) of the UI Workflow
