vue-smooth-dnd-next

Vue 3 Wrapper of smooth-dnd library.
Live demo

NOTE: This is a Vue 3 wrapper over smooth-dnd library. It's a fork of the already done vue2 wrapper done by the original author of the library.

All the documentation for the Vue 2 version works with this package version too!

npm install vue-smooth-dnd-next
