## When To Use
|
|
|
|
Transfer the elements between two columns in an intuitive and efficient way.
|
|
|
|
One or more elements can be selected from either column, one click on the proper `direction` button, and the transfer is done. The left column is considered the `source` and the right column is considered the `target`. As you can see in the API description, these names are reflected in.

|
## Warning
|
|
|
|
According the [standard](http://facebook.github.io/react/docs/lists-and-keys.html#keys) of React, the key should always be supplied directly to the elements in the array. In Transfer, the keys should be set on the elements included in `dataSource` array. By default, `key` property is used as an unique identifier.
|
|
|
|
If there's no `key` in your data, you should use `rowKey` to specify the key that will be used for uniquely identify each element.
|
|
|
|
```jsx
|
|
// eg. your primary key is `uid`
|
|
return <Transfer rowKey={record => record.uid} />;
|
|
```
