在Vue2或Vue3中项目中使用 Isotope（同位素） 过滤和排序神奇的布局神器，全网独家实现！

前言

Isotope是一个用于网格布局的JavaScript库，它可以帮助你创建漂亮的、动态的网格布局。Isotope支持过滤、排序和动画效果，可以让你的网站更加生动有趣。目前，不仅JQuery支持Isotope，还有Vue、React、Angular等这些框架也有对其进行封装，做成了组件，方便引入项目并使用。但是随着Vue等框架版本的升级，这些组件许多没有继续更新，不支持高版本的前端框架。也就是说在高版本前端框架的项目中引入许多年前的组件，或多或少会出现报错导致无法使用。于是，UP在此实现如何在Vue2或Vue3项目中使用 Isotope（同位素）神器，挺简单的，全网独家实现。
