DropDown태그가 안먹습니다

<Dropzone
        onDrop
        multiple 
        maxSize>
          {({getRootProps, getInputProps})=>{
            <div style={{width : '300px', height :'240px', border:'1px solid lightgray', display : 'flex',
                  alignItems:'center', justifyContent:'center'}} {...getRootProps()}
            >
             <input {...getInputProps()}/>
             <icon type="plus" style={{fontSize : '3rem'}}/>
            </div>
          }}
</Dropzone>
