Lastly - I've written an Autocomplete widget (as a workaround to the Dropdown issue above) . I'd parked it for a few months but have picked it up again. Whilst I seem to have most of the standard autocomplete functionality working - I can't seem to wire up the select/change events to update the backing model. Wondering if there are any examples on wiring up new ipywidgets with jquery (on 4.1.1). I've found an example on ipywidgets 5 - but having read the "compatability table" on the ipywidgets github page - I'm unsure as to whether I can upgrade the widgets to 5 whilst keeping the other jupyter components as per stock Anaconda 2.5.0 ? Any thoughts anyone ?
