Any element present in the original HTML host page can be used. Any element added to such elements via setInnerHTML would be usable too. The wrap() methods of widgets are designed for this use-case only: enhance existing markup. If you want a FormPanel for an element generated by your GWT app, then refactor to use a FormPanel *instead* of the element (instead of trying to "enhance" it later on) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
