## 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);
|
||
|
```
