控件前面添加icon
prefix-icon（首部）suffix-icon（尾部） 也可以通过 slot 来放置图标
<el-input placeholder="请选择日期" suffix-icon="el-icon-date" v-model="input1"> </el-input> <el-input placeholder="请输入内容" prefix-icon="el-icon-search" v-model="input2"> </el-input>
input 混合控件，select不显示，可能是width不够
<el-input placeholder="请输入内容" v-model="input3" class="input-with-select"> <el-select v-model="select" slot="prepend" placeholder="请选择"> <el-option label="餐厅名" value="1"></el-option> <el-option label="订单号" value="2"></el-option> <el-option label="用户电话" value="3"></el-option> </el-select> <el-button slot="append" icon="el-icon-search"></el-button> </el-input>
