In rare situations a component may want to change the props of a component that it doesn't own (like changing the className of a component passed as this.props.children). Other times it may want to make multiple copies of a component passed to it. cloneWithProps() makes this possible.

ReactComponent React.addons.cloneWithProps(ReactComponent component, object? extraProps)

Do a shallow copy of component and merge any props provided by extraProps. Props are merged in the same manner as transferPropsTo(), so props like className will be merged intelligently.

Note:

cloneWithProps does not transfer the key prop to the cloned component. If you wish to preserve the key, add it to the extraProps object:

var clonedComponent = cloneWithProps(originalComponent, { key : originalComponent.props.key });
