小編給大家分享一下小程序實現折疊菜單效果的示例代碼，希望大家閱讀完這篇文章之后都有所收獲，下面讓我們一起去探討吧！
通常，菜單都有一級菜單二級、三級菜單之分，我們知道前端js的dom操作可以很好的控制二級菜單的顯示與隱藏，當然今天我就不介紹web端的菜單折疊效果。我今天呢，是來學習學習小程序中該如何實現點擊一級菜單顯示/隱藏二級菜單，并且在點擊一個菜單顯示之外，要實現其他菜單隱藏。
實現效果如下：
代碼如下：
.wxml文件
<view class="cells">
<view class="item" wx:for="{{List}}" wx:for-index="idx" wx:for-item="item" wx:key="idx">
<view bindtap="isOpen" class="cdn" data-index="{{item.id}}">
<view>
<image class="img" src="{{item.iamges}}" mode="aspectFill"/><text class="content">{{item.cont}}</text>
</view>
<view>
<text class="discount">{{item.discount}}</text><image class="icon_img" src="{{item.hidden ? '/assets/icon_down2x.png' : '/assets/icon_up2x.png'}}" mode="aspectFill"/>
</view>
</view>
<view hidden="{{item.hiddena}}" class="hidden">
<block wx:for="{{item.invalidActivty}}" wx:for-index="index" wx:for-item="items" wx:key="index">
<view class="buys">
<view class="v1 ">
<navigator><text class="new-price">{{items.price}}</text><text class="oldPrice">{{items.oldPrice}}</text></navigator>
<navigator><text class="buy">{{items.validType}}</text><text style="font-size: 24rpx;margin-left: 20rpx;color: #6C6C6C">{{items.validTime}}</text></navigator>
</view>
<view class="shopping">
<text>購買</text>
</view>
</view>
</block>
</view>
</view>
</view>.wxss文件如下：
