el-data下拉框被遮挡

1. • 先加上这个:append-to-body="false" 挂载本dom
2. • 加上方法@focus='visibleChangeCC'
3. • 更改类名popper-class="popper-chanchu"
4. • 写方法更改定位 靠右边就right = 0 靠左边就left = 0

   popper-class="popper-chanchu"
   @focus='visibleChangeCC'

visibleChangeCC(isopen){ if(isopen) { document.querySelector('.popper-chanchu').style['right'] = '0px' document.querySelector('.popper-chanchu').style['left'] = '' } },
