This is a new link for downloading the widget by Larry Stout (re-posted with Larry's permission 2/18/2017). The download link on his main description page Larrys Custom WAB Widgets and More and the individual widget pages is no longer accessible. See the my comment on any of these pages, or on the Web AppBuilder Developer Edition - Resource List (updated 5/13/2018) for a the updated links for all hist widgets on this page.
NOTE: These widgets were written for an earlier version of WAB developer edition so may not work without modifications with current developer edition versions. Larry has changed jobs and is not working/updating these. They are as-is, with no direct support from Larry, but others in the forums might be able to respond to questions. If anyone does update, please share so others can benefit. Thanks.
