<template>
  <n-space vertical>
    <n-select
      v-model:value="selectedValue"
      filterable
      placeholder="选择歌曲"
      :options="options"
    />
    <n-select
      v-model:value="selectedValues"
      multiple
      filterable
      placeholder="选择歌曲"
      :options="options"
    />
  </n-space>
</template>

<script>
import { defineComponent, ref } from 'vue'

export default defineComponent({
  setup () {
    return {
      selectedValue: ref(null),
      selectedValues: ref(null),
      options: [
        {
          label: 'Drive My Car',
          value: 'song1'
        },
        {
          label: 'Norwegian Wood',
          value: 'song2'
        },
        {
          label: "You Won't See",
