Hey @wylieconlon I think a lot of your defs got reversed. ?: for optional, : for required. Looks like a lot of them just need to be flipped.

Hi @snide I followed the optional/required definitions from the PropTypes documentation. If you see any specific properties I missed, could you comment on the lines? I don't see any.

[wylieconlon]

Specifically, the PropTypes indicate that these have defaults and are therefore optional:

hasDividers | bool | false | Change to true if you want horizontal lines between options. This is best used when options are multi-line.
fullWidth   | bool | false | Make it wide
compressed  | bool | false | Make it short
isInvalid   | bool | false | Provides invalid styling

The existing proptypes are the main source of whether a prop is required or optional (with the code itself as the true authority, but ideally the proptypes are correct!). For SuperSelect, only options is marked with isRequired - for some reason react-docgen doesn't pick this up and render it as such in the docs. Actually, it appears none of our required props are being picked up as such by react-docgen, edit: I was looking at components with no required props; it appears only EuiSuperSelect's options isn't being marked correctly I'll file an issue on that and take a look.

Props that do not have a default value listed in the props may still be optional as the component can compare with null to determine what to do.

Thanks, I'll make these changes

Small changelog issue, otherwise lgtm.

You'll need to move this back up to master so it doesn't get tied to an old release.
