补充说明
基于@yeylcom/vue-treeselect 我个人做了一点修改。

- 添加props: label
当树的options数组不完整，或者使用nodeId无法在options中找到对应的节点时,可以使用 label， 在找不到节点时，显示相应内容.

- Rich options & highly customizable
- Supports a wide range of browsers (see below)
- RTL support
Requires Vue 2.2+
Getting Started
It's recommended to install vue-treeselect via npm, and build your app using a bundler like webpack.
npm install --save @yeylcom/vue-treeselectThis example shows how to integrate vue-treeselect with your Vue SFCs.
<!-- Vue SFC -->
<template>
<div id="app">
<treeselect v-model="value" :multiple="true" :options="options" />
</div>
</template>
<script>
// import the component
import Treeselect from '@yeylcom/vue-treeselect'
// import the styles
import '@yeylcom/vue-treeselect/dist/vue-treeselect.css'
export default {
// register the component
components: { Treeselect },
data() {
return {
// define the default value
value: null,
// define options
options: [ {
id: 'a',
label: 'a',
children: [ {
id: 'aa',
label: 'aa',
}, {
id: 'ab',
label: 'ab',
} ],
}, {
id: 'b',
label: 'b',
}, {
id: 'c',
label: 'c',
} ],
}
},
}
</script>If you just don't want to use webpack or any other bundlers, you can simply include the standalone UMD build in your page. In this way, make sure Vue as a dependency is included before vue-treeselect.
<html>
<head>
<!-- include Vue 2.x -->
<script src="https://cdn.jsdelivr.net/npm/vue@^2"></script>
<!-- include vue-treeselect & its styles. you can change the version tag to better suit your needs. -->
<script src="https://cdn.jsdelivr.net/npm/@yeylcom/vue-treeselect@^0.4.0/dist/vue-treeselect.umd.min.js"></script>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@yeylcom/vue-treeselect@^0.4.0/dist/vue-treeselect.min.css">
</head>
<body>
<div id="app">
<treeselect v-model="value" :multiple="true" :options="options" />
</div>
</body>
<script>
// register the component
Vue.component('treeselect', VueTreeselect.Treeselect)
new Vue({
el: '#app',
data: {
// define the default value
value: null,
// define options
options: [ {
id: 'a',
label: 'a',
children: [ {
id: 'aa',
label: 'aa',
}, {
id: 'ab',
label: 'ab',
} ],
}, {
id: 'b',
label: 'b',
}, {
id: 'c',
label: 'c',
} ],
},
})
</script>

Browser Compatibility
- Chrome
- Edge
- Firefox
- IE ≥ 9
- Safari
It should function well on IE9, but the style can be slightly broken due to the lack of support of some relatively new CSS features, such as transition and animation. Nevertheless it should look 90% same as on modern browsers.
