div内容超出边界时如何自动显示滚动条？

overflow: 'auto'

return (
    <div style={{borderRadius: '8px', border: '2px dashed #333', height: props.height, overflow: 'auto'}}>
        <div style={{textAlign: 'left'}}>
            <label>{props.title}</label>
        </div>
        <div>
            {props.data.map((item, index) => (
                <div
                    key={`${index}-${item.type}-${item.value} `}
                    style={{
                        float: 'left',
                        display: 'inline-block',
                        borderRadius: '6px',
                        border: '2px solid #000',
                        margin: '8px',
                        padding: '4px',
                        backgroundColor: item.selected ? '#39fe40' : '',
                    }}
                >
                    {item.value}
                </div>
            ))}
        </div>
    </div>
);
