Really appreciate all these examples ... this was exactly what I needed to transition from the old react-popper implementation.

@jacobweber I'm happy to have helped :).

Yes, thanks also for this great library and for the autosuggest examples.
There may be a little bug though: when navigation with the arrow keys through the suggestions popper/paper will not scroll if the selected item is outside the visible area. Setting max-height and overflow-hidden: auto as suggested by the author did not work.
Only way I found to solve this is to omit the renderSuggestionsContainer function (styling by hand then)
