Hi, For anyone who is interested. After looking further into the Polymer code, it turns out to be a simple solution by modifying the 'paper-dropdown-menu.html' and add ' name="[[name]]" ' inside paper-input template to make it work. Otherwise, calling the req.body.name will never work I assume this is bug which should be fixed by Polymer team - just in my own opinion.
