el-select 下拉框选项文字过长解决方案
首先给下拉框设置类名，即popper-class属性，并且给el-option增加title属性
<el-select
v-model="item.portrayalItem"
v-loadmore="{ method: lazyItemList, item, index }"
multiple
filterable
remote
popper-class="dropDown-select"
>
<el-option
v-for="i in item.selectList"
:key="i.LabelID"
:label="i.LabelName"
:title="i.LabelName"
:value="i.LabelID"
></el-option>
</el-select>然后设置样式，注意要新开一个style标签
<style lang="scss">
.dropDown-select{
width: 0;
}
</style>
