自定义选项渲染

经过了很久的思考，我决定放弃支持 slot API。当然，还是提供自定义渲染选项的方式。(例子中是渲染函数，但是你可以直接使用 option 的 style 或 class 选项)

<n-select v-model:value="value" :options="options" />

import { resolveComponent, h } from 'vue'
import { MdMusicalNote as MusicIcon } from '@vicons/ionicons-v4'

function render (option, selected) {
  return [
    h(
      resolveComponent('n-icon'),
      {
        style: {
          verticalAlign: 'middle',
          marginRight: '4px'
        }
      },
      {
        default: () => h(MusicIcon)
      }
    ),
    option.label
  ]
}

export default {
  data () {
    return {
      value: null,
      options: [
        {
          type: 'group',
          name: 'Rubber Soul',
          render: (data) => [data.name, '(Cool!)'],
          children: [
            {
              label:
                "Everybody's Got Something to Hide Except Me and My Monkey",
              value: 'song0',
              disabled: true
            },
            {
              label: 'Drive My Car',
              value: 'song1'
            },
            {
              label: 'Norwegian Wood',
              value: 'song2'
            },
            {
              label: "You Won't See",
              value: 'song3',
              disabled: true
            },

            {
              label: 'The Word',
              value: 'song6'
            },
            {
              label: 'Michelle',
              value: 'song7',
              disabled: true
