Vue 2 select2 自定义标签模板

Question

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"。

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'
        }
    ]
  }
})

body {
  font-family: "Source Sans Pro", "Helvetica Neue", Arial, sans-serif;
}

h1,.muted {
  color: #2c3e5099;
}

h1 {
  font-size: 26px;
  font-weight: 600;
  text-rendering: optimizelegibility;
  -moz-osx-font-smoothing: grayscale;
  -moz-text-size-adjust: none;
}

#app {
  max-width: 30em;
  margin: 1em auto;
}

#app .dropdown li {
  border-bottom: 1px solid rgba(112, 128, 144, 0.1)
}

#app .dropdown li:last-child {
  border-bottom: none;
}

#app .dropdown li a {
  padding: 10px 20px;
  display: flex;
  width: 100%;
  align-items: center;
  font-size: 1.25em;
}

#app .dropdown li a .fa {
  padding-right: 0.5em;
}
