element-ui：el-autocomplete实现搜索结果多次点击不关闭弹框

实现需求

通过搜索，将搜索结果关联到当前页面的对象，原来点击一下就关联，弹框关闭

现在需要支持同一个搜索结果多次点击关联，加快处理速度

实现效果

实现思路

将捕获点击事件，并且阻止传播 @click.stop="handleItemClick(item)"，@select就不能收到点击事件，就不会关闭搜索结果了

还需要设置样式，将li 标签的padding值去掉，以免点击触发到结果项外边，保证结果项将整行都覆盖住

.mo-autocomplete {
      li {
          padding: 0;
      }
}
