【问题描述】：

我知道我可以更改option slot 的模板，但我们可以为标签槽做同样的事情吗？喜欢option：

  <v-select inputId="originsId" :options="origins" label="city" placeholder="Search...">
    <template slot="option" slot-scope="origin">
      <div class="flex">
        <div class="col">
          <span> origin.city </span>
        </div>
        <div class="col">
          <span> origin.country </span>
        </div>
      </div>
    </template>
  </v-select>

是否有某种方式我可以在选择选项时样式标签？现在它只显示label="city" 值。我需要类似的东西：

  <v-select inputId="originsId" :options="origins" label="city" placeholder="Search...">
    <template slot="label" slot-scope="origin">
      <div class="flex">
        <div class="col">
          <span>Selected city:  origin.city </span>
        </div>
        <div class="col">
          <span>Selected country:  origin.country </span>
        </div>
      </div>
    </template>

    <template slot="option" slot-scope="origin">
      <div class="flex">
        <div class="col">
          <span> origin.city </span>
        </div>
        <div class="col">
          <span> origin.country </span>
        </div>
      </div>
    </template>
  </v-select>

基本上我需要一些自定义样式和附加信息，然后选择选项时label="city"。

【参考方案1】：

作为Vue-select Github: L324 和Vue-select Github: L539，使用<slot name="selected-option"> 将是一种解决方案。

更新：从Vue-select Github 你会看到有一个父槽 = selected-option-container，但我发现它还没有部署到 dist .将来，您应该可以使用此插槽自定义整个容器和选定的选项。

如下演示：

Vue.component('v-select', VueSelect.VueSelect)

new Vue(
  el: '#app',
  data: 
    options: [
      
          title: 'Read the Docs',
          icon: 'fa-book',
          url: 'https://codeclimate.com/github/sagalbot/vue-select'
        ,
        
          title: 'View on GitHub',
          icon: 'fa-github',
          url: 'https://codeclimate.com/github/sagalbot/vue-select'
        ,
        
          title: 'View on NPM',
          icon: 'fa-database',
          url: 'https://codeclimate.com/github/sagalbot/vue-select'
        ,
        
          title: 'View Codepen Examples',
          icon: 'fa-pencil',
          url: 'https://codeclimate.com/github/sagalbot/vue-select'
        
    ]
  
)
