如何使用react-fine-uploader更改上传按钮的位置和预览缩略图

Question

我正在使用react-fine-uploader上传文件。所有工作正常，但我想改变位置上传按钮和预览缩略图，如按钮应位于页面底部，缩略图应位于身体中间的某个位置。

import React from 'react'
import ReactDOM from 'react-dom'
import FileInput from 'react-fine-uploader/file-input' 
import FineUploaderTraditional from 'fine-uploader-wrappers' 
const uploader = new FineUploaderTraditional({ options: { request: { endpoint: 'my/upload/endpoint' } } }) 
const fileInput = ( <FileInput multiple accept='image/*' uploader={ uploader }> <span class="icon ion-upload">Choose Files</span> </FileInput> )
ReactDOM.render( fileInput, document.getElementById('content') )
