/**
|
|
* The `<TransitionGroup>` component manages a set of `<Transition>` components
|
|
* in a list. Like with the `<Transition>` component, `<TransitionGroup>`, is a
|
|
* state machine for managing the mounting and unmounting of components over
|
|
* time.
|
|
*
|
|
* Consider the example below using the `Fade` CSS transition from before.
|
|
* As items are removed or added to the TodoList the `in` prop is toggled
|
|
* automatically by the `<TransitionGroup>`. You can use _any_ `<Transition>`
|
|
* component in a `<TransitionGroup>`, not just css.
|
|
*
|
|
* ```jsx
|
|
* import TransitionGroup from 'react-transition-group/TransitionGroup';
|
|
*
|
|
* class TodoList extends React.Component {
|
|
* constructor(props) {
|
|
* super(props)
|
|
* this.state = {items: ['hello', 'world', 'click', 'me']}
|
|
* }
|
|
* handleAdd() {
|
|
* const newItems = this.state.items.concat([
|
|
* prompt('Enter some text')
|
|
* ]);
|
|
* this.setState({ items: newItems });
|
|
* }
|
|
* handleRemove(i) {
|
|
* let newItems = this.state.items.slice();
|
|
* newItems.splice(i, 1);
|
|
* this.setState({items: newItems});
|
|
* }
|
|
* render() {
|
|
* return (
|
|
* <div>
|
|
* <button onClick={() => this.handleAdd()}>Add Item</button>
|
|
* <TransitionGroup>
|
|
* {this.state.items.map((item, i) => (
|
|
* <FadeTransition key={item}>
|
|
* <div>
|
|
* {item}{' '}
|
|
* <button onClick={() => this.handleRemove(i)}>
|
|
* remove
|
|
* </button>
|
|
* </div>
|
|
* </FadeTransition>
|
|
* ))}
|
|
* </TransitionGroup>
|
|
* </div>
|
|
* );
|
|
* }
|
|
* }
|
|
* ```
|
|
*
|
|
* Note that `<TransitionGroup>` does not define any animation behavior!
|
|
* Exactly _how_ a list item animates is up to the individual `<Transition>`
|
|
* components. This means you can mix and match animations across different
|
|
* list items.
