office-ui-fabric-react upload file compoment and country-region-selector abscent

how can get the "upload file" and "country-region-selector" compoments in office-ui-fabric-react. it seems that office Ui fabric doesnot have those compoments.

on React there is only this https://www.npmjs.com/package/react-upload-file for the "upload file" and this  for the "country-region-selector" 

but not with css of office UI fabric ?

any idea how to adapt those react native compoments to Office UI fabric or is there any compoments on Office-UI-Fabric, and how can we explore the file with adding it to list.

thank you.
