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

ReactElement React.addons.cloneWithProps(ReactElement element, object? extraProps)

Do a shallow copy of element and merge any props provided by extraProps. The className and style props will be merged intelligently.

Note:

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

var clonedElement = cloneWithProps(originalElement, { key : originalElement.key });

ref is similarly not preserved.
