Here at Wertarbyte, we're using Material-UI for many of our projects.
It already includes a lot of components, but sometimes you need a more complex composed component (e.g. a chip input or a time picker) or something very basic (e.g. dots for pagination).
This is our collection of such components. Every component is maintained in its own repository and published as independent npm package. This way, we hope to give every component the amount of love and care it deserves to make it as good as possible.
If you have a question or a suggestion or found a bug, please tell us using the issue tracker of the related GitHub project. We're also always happy to receive pull requests.
These components only work with Material-UI 1.0.0 or later. If you're still using the legacy version (e.g. 0.20.0), don't worry, we still have many components for you. In fact, not all of our components are ported yet, but we're working on that.
