The new Form feature in Google Colaboratory

Question

Can someone explain or give a notebook example how to use the new Form feature? It looks really exciting, but I cannot find any example or even an announcement anyw

Answer 1

It seems to be an in-development feature. I noticed it a couple of days ago, on a refraction doc I was using in-class with students, and assumed it was because I'd imported matplolib, which I've not had reason to do before.

I reloaded the doc later to have a closer look, but the 'form' and 'field' buttons had disappeared from the mouseover menu.

I know I was not dreaming because the

@title

attribute was still there!

I just opened an unrelated student doc now to mark it and the additional menu items are there. No matplotlib in this doc, just basic Python.
