cc'ing media router OWNERs.

Could you provide some instrucitons on how to launch the media router WebUI locally, so that I can replace paper-menu wit paper-listbox? Thank you.

Just discovered that navigating to chrome://media-router works (although probably does not look exactly as in the normal in-dialog UI).

You can open the Media Router dialog via the overflow menu ('Cast...', right below 'Print...' or also often via the right click context menu (although that is context dependent).

Even without any Cast devices the relevant UI elements should be in the dialog header IIUC.

@amp: Thanks for the pointer. One more question.

I am only able to see the first paper-menu instance, see [1]. Is there a way to easily invoke the 2nd (#sink-list-paper-menu) and 3rd  (#search-results-paper-menu) instances?

I can't recall exactly which instance correspond to which modes of the dialog.

If you run on canary there should be a couple of 'test' devices which should populate the sink list (I think, I haven't run canary in a while, there should be a way to run a dev version of the media router component extension which should also have the test sinks).

Search entry field will only show up on Chrome (not Chromium) and with a signed in account which is part of a domain (so not regular gmail account).

IIRC, others more familiar with the dialog internals might be able to give better guidance.
