Why is there no tooltip property for raised and flat buttons?

Question

I often need the tooltip property to explain why a button is disabled, any reason why there is no support for that?

Answer 1

Mostly for the same reason other features we'd like to include are currently unsupported.

Material-UI is developed almost exclusively by volunteers, and community contributors on their own time, so we have to pick and choose what to focus on.

We have talked about exposing Tooltip as a documented public component, but that will take work to clean up and document the API, and test it for use outside Material-UI components. At that point you'll be able to add a tooltip to a Button or anything else.

It's unlikely this will happen prior to the styles re-write that is targeted for the next breaking release, or the patch releases that will almost inevitably follow that major overhaul.
