最近为了实现课程设计，也做了一些前端的东西，今天想要做一个联动菜单来实现一些功能。实现了，也来做做笔记。

第1步：了解一下

左右侧菜单其实简单来讲就是把一个区域分成左右两个部分。关于组件，我觉得可以直接去微信开发文档看。通过代码，我觉得应该是可以理解的。话步多讲，直接上代码。（首先说明一点的是，我还是个刚刚接触前端的小白，可能有些写得不太好得，往各位博友多多指出改进得建议，相互学习）

第2步：先看一下效果啦

运行效率还是可以的很快，无卡顿现象。

第3步：实现（代码）

这里我只放了其中一部分，也是可以直接实现的，没有问题，可以根据自己的需要修改。

wxml


<!-- 左侧滚动栏 -->
<view class ='total'>
<view class='under_line'></view>
<view style='float: left' class='left'>
  <scroll-view scroll-y scroll-with-animation scroll-left="{{scrollLength}}" class='scrollY' style='height: {{winHeight}}px'>
    <view class='all clear'>
      <block wx:key="lists" wx:for="{{lists}}">
        <view bindtap='jumpIndex' data-menuindex='{{index}}'>
          <view class='text-style'>
            <text class="{{indexId==index?'active1':''}}">{{item}}</text>
