## zh-CN
使用 `height` 属性则切换为虚拟滚动。
## en-US
Use virtual list through `height` prop.
```jsx
import { Tree } from 'antd';
function dig(path = '0', level = 3) {
const list = [];
for (let i = 0; i < 10; i += 1) {
const key = `${path}-${i}`;
const treeNode = {
title: key,
key,
};
if (level > 0) {
treeNode.children = dig(key, level - 1);
}
list.push(treeNode);
}
return list;
}
const treeData = dig();
ReactDOM.render(<Tree treeData={treeData} height={233} defaultExpandAll />, mountNode);
```
