严重的UI Selectfield问题

Question

我正在尝试更改material-ui selectfield的按钮位置。但没有这样做。你们中有人遇到这个问题吗？ 我想访问material-ui selectfield按钮的top属性。怎么做？

我分享了以下屏幕截图：

我有以下代码。谁能帮忙解决这个问题？

import React, { Component } from 'react';
import TextField from 'material-ui/TextField';
import SelectField from 'material-ui/SelectField';
import MenuItem from 'material-ui/MenuItem';
import Dialog from 'material-ui/Dialog';

const styles = {
    floatingGlamNameLabelFocusStyle: {
       color: '#A1A1A1',
       top:'38px'
    },
    floatingPhoneStyle: {
        top: '20px',
        color: '#A1A1A1'
    },
    nameTextStyle: {
        color: '#A1A1A1', 
        fontFamily: 'Muli', 
        fontSize: '14px', 
        fontWeight: 'bold'
    }
};
const hintGlamGenderStyle = {

                                                >
                                 {items}
                             </SelectField>
                          </div>
                        </div>
                     <div className="col-sm-6">

                </div>
            </div>
        );
    }
}

export default GlamUpload;
