vue2-lazy-tree

first of all, i highly recommended to see the demo

and u will find out how to use this plugin

i must say, this doc is terrible, but the function is really good

features

• node issue tip

• normal tree

• lazy loading

• loading tip

• dynamic add node

• custom tree icon, use iconFont

• custom icon style. color

• ie9,10,11,spartan

notice:

del search function

because the chinese-to-pinyin package too large, and you can achieve u own search or filter function， so i del this useless func

loadingChild method

import { ZTree, ComboZTree, generateKey, getParentNode } from 'vue2-lazy-tree'

import ZTree from 'vue2-lazy-tree'

Build Setup

# install dependencies
npm install

# serve with hot reload at localhost:8080
npm run dev

# build for production with minification  publish to npm
npm run build

---

How to install the plugin

  npm install vue2-lazy-tree or cnpm install vue2-lazy-tree (国内)

How to use in u production

import { ZTree } from 'vue2-lazy-tree/dist/vue2-tree.min'
