vue-tree-file-list

A vue component for tree structure supports adding treenode/leafnode, editing node's name and dragging.

Thank ParadeTo who is the original author, I just add some new functions to it.

Here is the original address : https://www.npmjs.com/package/vue-tree-list

use

npm install vue-tree-file-list

<button @click="addNode">Add Node</button>
<vue-tree-file-list @click="onClick" :model="data" default-tree-node-name="new node" default-leaf-node-name="new leaf"></vue-tree-file-list>
<button @click="getNewTree">Get new tree</button>
<pre>
  {{newTree}}

Forbid dragging
