This is what the docs website looks like on my screen:

There are "disabled" scrollbars on each sidebar item. This is a result of overflow: 'scroll' being applied to a wrapping <div> element on each one, and it doesn't need to be there. Even for the "onChangeComplete" item, which does have a working horizontal scrollbar, it is entirely because the vertical scrollbar itself is taking up space it could be using. When I remove scrollbars, it looks much better (and perhaps as expected):

I am not sure how to make this change without affecting the react-material-design library itself.
A further note is the code samples on the right column, which are also displaying these phantom scrollbars. In these cases using overflow: 'auto' will work just fine, as the disabled scrollbars will not appear unless they are actually needed.
Ah! I am on a mac so I never knew this was an issue! Thanks, I will look into it!
I'm also on a Mac! However in some cases the scroll bars turn on - On my work machine I have "Always show scrollbars" turned on and I believe it may always show if you connect a Macbook to an external display.
Oh cool, I had no idea, so I can recreate this to get it to go away, killer!
