2) Delete the widget.jsp and replace with a widget.html like the following:
3) Create a client library with a category of af.customwidgets.
4) In the client library add code as follows:
5) Change the CLASS_FOR_YOUR_TEXTBOX and YOUR_WIDGETNAME
6) Add listeners for when text is entered and perform JS code for "auto suggest" feature
