请问vue框架基于elementui库的输入框选择器的样式如何调整？

Question

如图，那个选择器的控件偏向了最左边，我怎么移动都移不过来

我想要实现的是上图的效果，将一个图标置于选择器处，点击下拉键后就可以展开整个列表，请赐教，不胜感激。

<template>
<div id="search">
  <el-input placeholder="请输入内容" v-model="input3" class="input-with-select" :style="
  {height: '100%'}">
    <el-select v-model="select" slot="prepend">

      <el-option value="1" :style="{display:'inline-block',height:'70px'}">
        <slot>
          <img src="../assets/baidu.png" title="百度" alt="百度"/>
        </slot>
      </el-option>
      <el-option value="2" :style="{display:'inline-block',height:'70px'}">
        <slot>
          <img src="../assets/google.png" title="谷歌" alt="谷歌"/>
        </slot>
      </el-option>
      <el-option value="3" :style="{display:'inline-block',height:'70px'}">
        <slot>
          <img src="../assets/juejin.png" title="掘金" alt="掘金"/>
        </slot>
      </el-option>
    </el-select>
<!--    <el-button slot="append" icon="el-icon-search"></el-button>-->
  </el-input>
