竖向Tab效果

uniapp并不提供竖向tab组件,需要我们自定义组件。

1.项目结构图

2.items/index.vue

<template>
    <view>
        <view class="scroll-view-container">
            <!-- 左侧滑动区域 -->
            <scroll-view scroll-y="true" class="left-scroll-view" :style="{height: wh + 'px'}">
                <block v-for="(c,i) in catalogList" :key="c.id">
                    <view :class="['left-scroll-view-item',c.id === active ? 'active' : '']"
                        @click="activeChanged(c.id)">
                        {{c.cname}}
                    </view>
                </block>
            </scroll-view>
            <!-- 右侧滑动区域 -->
