Usage

Notes:

1. when using rem to layout, calculate the width after adaptation before passing the value.
2. Use the parent component of 'waterfall' if there is a problem with the style, remove CSS scoped and try it

main.js

import { createApp } from "vue";
import waterfall from 'vue-waterfall2'

const app = createApp(App)
app.use(waterfall)

app.vue

<template>
  <div class="container-water-fall">
    <div><button  @click="loadmore">loadmore</button> <button @click="mix">mix</button> <button @click="switchCol('5')">5列</button> <button @click="switchCol('8')">8列</button> <button @click="switchCol('10')">10列</button> </div>

    <waterfall :col='col' :width="itemWidth" :gutterWidth="gutterWidth"  :data="data"  @loadmore="loadmore"  @scroll="scroll"  >
      <div class="cell-item" v-for="(item,index) in data">
        <div class="item-body">
            <div class="item-desc">{{item.title}}</div>
            <div class="item-footer">
                <div class="avatar" :style="{backgroundImage : `url(${item.avatar})` }"></div>
                <div class="name">{{item.user}}</div>
                <div class="like" :class="item.liked?'active':''" >
                    <i ></i>
                    <div class="like-total">{{item.liked}}</div>  
                </div>
            </div>
        </div>
      </div>
