The content of this article is about small program examples: small programs realize the effect of folding menus (with code), which has certain reference value. Friends in need can refer to it. I hope it will be helpful to you. .

Usually, menus are divided into first-level menus, second-level menus, and third-level menus. We know that the DOM operation of front-end js can well control the display and hiding of second-level menus. Of course, I will not do that today. Introducing the menu folding effect on the web side. Today, I am here to learn how to implement clicking on the first-level menu in Mini Program Show/Hidesecond-level menu, and in addition to clicking on a menu to display, other menus must be implemented hide.

The effect is as follows:

The code is as follows:

.wxml file

<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 ? &#39;/assets/icon_down2x.png&#39; : &#39;/assets/icon_up2x.png&#39;}}" 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>购买</text>
                    </view>
                </view>
            </block>
        </view>
