Props

tag: PropTypes.string

The wrapping element around your only child element. Defaults to div. Any other valid props like className will be passed to this element.

height: PropTypes.oneOf(['auto', PropTypes.number])

The height value you want to animate to. Defaults to auto.

rmConfig: React.PropTypes.objectOf(React.PropTypes.number)

Pass in any valid React Motion config object.

children: PropTypes.node.isRequired (only one child allowed)

Only one child is allowed and is what the measurements will be based off of. This should be considered a pretty "dumb" element that is just a wrapper to measure off of. Make sure there are no margins are "hanging" outside of your elements. You can use 1px padding to avoid this.

beforeAnimation: PropTypes.func(currentHeight, nextHeight)

Callback before animation has started. Passes in previous and next heights.

afterAnimation: PropTypes.func

Callback after animation has completed.
