How to use

Step1: install plugins (Vue Cli3 not necessary, Demo based on VueCli3)

npm install babel-plugin-syntax-jsx babel-plugin-transform-vue-jsx babel-helper-vue-jsx-merge-props babel-preset-env --save-dev

npm install vue-tree-halower  --save

Step2: In your .babelrc (Vue Cli3 not necessary,Demo based on VueCli3)

{
  "presets": ["env"],
  "plugins": ["transform-vue-jsx"]
}

Step3： In your main.js

import 'vue-tree-halower/dist/halower-tree.min.css' // you can customize the style of the tree
import VTree from 'vue-tree-halower'

Vue.use(VTree)
