Full height selection

[Swazimodo]

If you look at material-ui's multi select control. When the menu opens it takes up the full height of the screen to make the options easy to sort through. Right now if you open your select component the menu can show up off the bottom of the screen. If you adjust the window or scroll it the menu seems to jump around and try to stay in frame.

I think this select would be pretty much perfect if it had the ability to go full height like the material one I was comparing it to. Especially on mobile devices it would give a much better user experience.

I think what you need to do is put your menu in a popover to get this effect.
