react-overlays - Utilities for creating robust overlay components
All of these utilities have been abstracted out of react-bootstrap in order to provide better access to the generic implementations of these commonly needed components. The included components are building blocks for creating more polished components. Everything is bring-your-own-styles, css or otherwise. If you are looking for more complete overlays, modals, or tooltips--something you can use right out of the box--check out react-bootstrap, which is (or soon will be) built on using these components.
