Google Drive / Dropbox FilePicker Portlet.

I added a Google Drive / Dropbox FilePicker Portlet.  The portlet uses the FilePicker API to access Google Drive and DropBox.  Also, I am using bootstrap so I added that to be part of the  "resource sharing" config in pom.
How does the document have an element with id=result?  I don't see it in the jsp... is it created dynamically somehow?
