Virtual scrolling to improve performance of Options #771
Description
There are some issues opened about react-select performance, when it is used with a lot of options.
Main problem is simply that it renders a
for each option, even if you have more than 500 options (In my case I have more than 2000 options).
The best solution would be to use the "virtual scrolling" (sometimes called "buffered scrolling"): it's the technique used for large Data Tables.
It practically renders only a part of the options (50 of them for example), while it simulates all the others with one large and empty
(so that the vertical scrollbar is always consistent).

It would be awesome to have it in react-select!
