ueditor百度富文本编辑器粘贴后html后丢失class和style样式问题

有时用css排版做了了排版和样式，html加了class复制粘贴到ueditor百度富文本编辑器后，发面html后丢失class和style，自动被过滤掉了。如何保留粘贴后的html标签classs和style呢。

原效果图：

原代码：

<div class="car-list">
    <ul class="row">
        <li class="col-md-4">
            <div class="car-box">
                <img  src="/static/images/car/car1.png" alt="5 seats car">
                <h3>5 seats car</h3>
                <div class="price-info">
                    <p>One day City Tour                          <span>$120</span></p>
                    <p>Airport/Train Transfer                     <span>$25</span></p>
                    <p>One day Heavenly Lake Tour         <span>$130</span></p>
                    <p>One day Turpan Tour                     <span>$150</span></p>
                    <p>Northern/Southern Xinjiang Tour    <span>$180/day</span></p>
                </div>
            </div>
        </li>

        <li class="col-md-4">
            <div class="car-box">
                <img  src="/static/images/car/car2.png" alt="SUV">
                <h3>SUV</h3>
                <div class="price-info">
                    <p>One day City Tour                        <span>$130</span></p>
                    <p>Airport/Train Transfer                    <span>$30</span></p>
                    <p>One day Heavenly Lake Tour        <span>$150</span></p>
                    <p>One day Turpan Tour                    <span>$ 200</span></p>
                    <p>Northern/Southern Xinjiang Tour   <span>$200/day</span></p>
                </div>
            </div>
        </li>
        

    </ul>
</div>

复制粘贴到ueditor编辑器里后，div ul li中的class等都被过滤不见了，导致样式排版没有了。

解决办法是，找到ueditor.config文件，找到section那项，把class和style加入白名单section:['class', 'style']，ul:['class', 'style'],li:['class', 'style'],

找到allowDivTransToP:truea，设置为true
