Ant DesignTransfer
Double column transfer choice box.
When To Use#
It is a select control essentially which can be use for selecting multiple items.
Transfer can display more information for items and take up more space.
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.
Examples

The most basic usage of Transfer involves providing the source data and target keys arrays, plus the rendering and some callback functions.
import React, { useState } from 'react';
import { Transfer } from 'antd';
const mockData = [];
for (let i = 0; i < 20; i++) {
mockData.push({
key: i.toString(),
title: `content${i + 1}`,
description: `description of content${i + 1}`,
});
}
const initialTargetKeys = mockData.filter(item => +item.key > 10).map(item => item.key);
const App = () => {
const [targetKeys, setTargetKeys] = useState(initialTargetKeys);
const [selectedKeys, setSelectedKeys] = useState([]);
const onChange = (nextTargetKeys, direction, moveKeys) => {
console.log('targetKeys:', nextTargetKeys);
console.log('direction:', direction);
console.log('moveKeys:', moveKeys);
setTargetKeys(nextTargetKeys);
};
const onSelectChange = (sourceSelectedKeys, targetSelectedKeys) => {
console.log('sourceSelectedKeys:', sourceSelectedKeys);
console.log('targetSelectedKeys:', targetSelectedKeys);
setSelectedKeys([...sourceSelectedKeys, ...targetSelectedKeys]);
};
const onScroll = (direction, e) => {
console.log('direction:', direction);
console.log('target:', e.target);
};
return (
<Transfer
dataSource={mockData}
titles={['Source', 'Target']}
targetKeys={targetKeys}
selectedKeys={selectedKeys}
onChange={onChange}
onSelectChange={onSelectChange}
onScroll={onScroll}

);
};

Use oneWay to makes Transfer to one way style.
import { Transfer, Switch } from 'antd';
const mockData = [];
for (let i = 0; i < 20; i++) {
mockData.push({
key: i.toString(),
title: `content${i + 1}`,
description: `description of content${i + 1}`,
disabled: i % 3 < 1,
});
}
const oriTargetKeys = mockData.filter(item => +item.key % 3 > 1).map(item => item.key);
class App extends React.Component {
state = {
targetKeys: oriTargetKeys,
selectedKeys: [],
disabled: false,
};
handleChange = (nextTargetKeys, direction, moveKeys) => {
this.setState({ targetKeys: nextTargetKeys });
console.log('targetKeys: ', nextTargetKeys);
console.log('direction: ', direction);
console.log('moveKeys: ', moveKeys);
};
handleSelectChange = (sourceSelectedKeys, targetSelectedKeys) => {
this.setState({ selectedKeys: [...sourceSelectedKeys, ...targetSelectedKeys] });
console.log('sourceSelectedKeys: ', sourceSelectedKeys);
console.log('targetSelectedKeys: ', targetSelectedKeys);
};
handleScroll = (direction, e) => {
console.log('direction:', direction);
console.log('target:', e.target);
};
handleDisable = disabled => {
this.setState({ disabled });
};
render() {
const { targetKeys, selectedKeys, disabled } = this.state;

ReactDOM.render(<App />, mountNode);Advanced Usage of Transfer.
You can customize the labels of the transfer buttons, the width and height of the columns, and what should be displayed in the footer.
import { Transfer, Button } from 'antd';
class App extends React.Component {
state = {
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,
};
if (data.chosen) {
targetKeys.push(data.key);
}
mockData.push(data);
}
this.setState({ mockData, targetKeys });
};
handleChange = targetKeys => {
this.setState({ targetKeys });
};
renderFooter = (props, { direction }) => {
if (direction === 'left') {
return (
<Button size="small" style={{ float: 'left', margin: 5 }} onClick={this.getMock}>
Left button reload
</Button>
);
}
return (
<Button size="small" style={{ float: 'right', margin: 5 }} onClick={this.getMock}>
Right button reload
</Button>
);
};
render() {
return (
<Transfer
dataSource={this.state.mockData}
showSearch
listStyle={{
width: 250,
height: 300,
}}
operations={['to right', 'to left']}
targetKeys={this.state.targetKeys}

<Transfer {...props}>{listProps => <YourComponent {...listProps} />}</Transfer>Warning#
According the standard 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.
// eg. your primary key is `uid`
return <Transfer rowKey={record => record.uid} />;FAQ#
