你需要确保引用的是同一个对象：http://jsfiddle.net/leopoldthecuber/vcgftLvn/10/

@Leopoldthecoder 如果是远程搜索 搜索怎么保证同一个对象？

那么目前是无法做到的。因为对于一个没有存在于 options 中的 value，Select 是不知道需要把 value 的哪个字段显示出来的（所以你看到的是空白）。

如果 value 的值是字符串或数字，那么 Select 会把它本身显示出来。

@Leopoldthecoder 为什么不能做成像https://github.com/monterail/vue-multiselect/tree/2.0这样
其实不一定要同一对象才能初始化。
vue-multiselect 在传入value的情况下

根据你填写的label把对应的value显示出来就好了

2.13.2版本后，在el-select元素上加上属性value-key="key"，即可
