TreeChecked 树形选择控件
使用树选择控件可以完整展现其中的层级关系,并具有选中状态。
import { TreeChecked } from 'uiw';
import TreeChecked from '@uiw/react-tree-checked';
基础实例
import ReactDOM from 'react-dom';
import { TreeChecked, Card, Row, Col } from 'uiw';
const data = [
{
label: '湖北省',
key: '0-0-0',
children:[
{
label: '武汉市',
key: '0-1-0',
children:[
{ label: '新洲区', key: '0-1-1', disabled: true },
{ label: '武昌区', key: '0-1-2' },
{
label: '汉南区',
key: '0-1-3',
children:[
{ label: '汉南区1', key: '0-1-3-1' },
{ label: '汉南区2', key: '0-1-3-2' },
{ label: '汉南区3', key: '0-1-3-3' },
]
},
]
},
{ label: '黄冈市', key: '0-2-0' },
{
label: '黄石市',
key: '0-3-0',

const Demo = () => (
<TreeChecked
data={data}
selectedKeys={['0-1-1']}
onExpand={(key, expanded, data, node) => {
console.log(key, expanded, data, node);
}}
