建议重写
<div class="next-balloon"><!--MegaMenu容器-->
<div class="sc-hd-m-droplist"><!--MegaMenu本体，这个带背景图片-->
<a class="sc-hd-m-menu"><!--MegaMenu菜单项-->
<img src="菜单项图片地址，也可以写进a.sc-hd-m-menu里的背景图片">
<span class="sr-only" hidden>可选隐藏文字</span>
</a><!--更多菜单项略-->
</div>
</div>

加个a不就好了

外面包个a就可以了要不然你把图片当li加背景也可以
