Usage

Install

npm install --save el-select-tree

Require element-ui

If your project does not use element-ui, you need to introduce a separate element-ui package, like this:

import 'el-select-tree/lib/element-ui';

Global registration

import Vue from 'vue';
import ElSelectTree from 'el-select-tree';

Vue.use(ElSelectTree);

In-component registration

import ElSelectTree from 'el-select-tree';

export default {
  components: {
    ElSelectTree
  }
};

Complete example

<template>
  <el-select-tree
    width="120px"
    placeholder="请选择内容"
    :data="treeData"
    v-model="value"
  ></el-select-tree>
</template>

<script>
import ElSelectTree from 'el-select-tree';

export default {
  components: {
    ElSelectTree
  },
  data() {
    return {
      value: 2,
      treeData: [
        {
          value: 1,
          label: 'text1',
          children: [{ value: 5, label: 'text5' }, { value: 6, label: 'text6' }]
        },
