Autocompleteinput of bokeh 0.12.13 does not work at all . I tested on Chrome browser 63.0.3239.108, the latest as of now.
Although it had bugs, it used to work in bokeh 0.12.9.
Without this, it is very frustrating experience to select an item from a plain dropdown menu, when the menu has a very long list of items.
I wonder if there is any plan to support it fully.
