I want the user to be able to see the full drop down when nothing typed
It looks like bootstrap does this when min-length is 0 - focus gives the full drop down
However, this approach doesn't seem to work in the AngularJS version.
is there a way to display the full dropdown?
(I looked at code, I suspect that typeahead-min-length='0' resets the min-length to 1 based on the $eval)
