antd4 TreeSelect树选择关闭虚拟滚动

TreeSelect的虚拟滚动属性是默认打开的，可视区加载10条数据。
如果你想关掉的话，可以设置dropdownMatchSelectWidth为false,就会加载所有的数据，不是动态加载。
代码如下：

import React, {
    
     useState } from 'react';
import {
    
     TreeSelect } from 'antd';

const {
    
     TreeNode } = TreeSelect;

const Demo = () => {
    
    
  const [value, setValue] = useState(undefined);
  const onChange = () => {
    
    
    setValue(value);
  };
  return (
    <TreeSelect
      dropdownMatchSelectWidth={
    
    false}//关闭虚拟滚动
      showSearch
      style={
    
    {
    
     width: '100%' }}
      value={
    
    value}
      dropdownStyle={
    
    {
    
     maxHeight: 400, overflow: 'auto' }}
      placeholder="Please select"
      allowClear
      treeDefaultExpandAll
      onChange={
    
    onChange}
    >
      <TreeNode value="parent 1" title="parent 1">
        <TreeNode value="parent 1-0" title="parent 1-0">
          <TreeNode value="leaf1" title="leaf1" />
          <TreeNode value="leaf2" title="leaf2" />
        </TreeNode>
        <TreeNode value="parent 1-1" title="parent 1-1">
          <TreeNode value="leaf3" title={
    
    <b style={
    
    {
    
     color: '#08c' }}>leaf3</b>} />
        </TreeNode>
      </TreeNode>
    </TreeSelect>
  );
};

ReactDOM.render(<Demo />, mountNode);
