## zh-CN
|
||
|
||
自定义渲染每一个 Transfer Item，可用于渲染复杂数据。
|
||
|
||
## en-US
|
||
|
||
Custom each Transfer Item, and in this way you can render a complex datasource.
|
||
|
||
````__react
|
||
import { Transfer } from 'antd';

||
|
||
const App = React.createClass({
|

getInitialState() {

mockData: [],
|
||
targetKeys: [],

||
},

||
componentDidMount() {
|
||
this.getMock();
|
||
},
|
||
getMock() {
|
||
const targetKeys = [];
|
||
const mockData = [];
|
||
for (let i = 0; i < 20; i++) {
|
||
const data = {
|
||
key: i.toString(),
|
||
title: `content${i + 1}`,
|
||
description: `description of content${i + 1}`,
|
||
chosen: Math.random() * 2 > 1,
|

};
|
