### 基础用法
适用广泛的基础单选
<el-button @click="bb">bb</el-button>
:::demo `v-model`的值为当前被选中的`el-option`的 value 属性值
```html
<template>
<el-select v-model="value" placeholder="请选择">
<el-select v-model="value" placeholder="请选择" @change="aa">
<el-option
v-for="item in options"

### 远程搜索
从服务器搜索数据，输入关键字进行查找
<el-button @click="empty">aa</el-button>
:::demo 为了启用远程搜索，需要将`filterable`和`remote`设置为`true`，同时传入一个`remote-method`。`remote-method`为一个`Function`，它会在输入值发生变化时调用，参数为当前输入值。需要注意的是，如果`el-option`是通过`v-for`指令渲染出来的，此时需要为`el-option`添加`key`属性，且其值需具有唯一性，比如此例中的`item.value`。
```html
<template>
<el-select
v-model="value9"
multiple
clearable
filterable
remote
placeholder="请输入关键词"
