Vuejs單擊打開按鈕時如何顯示選擇列表

越光新鮮

我是這樣寫的，但是當我按下按鈕時，所有組合框都會出現，但我希望當我按下任何組合框中的按鈕時，只有組合框才會出現
HTML

             <div class="m-combobox">
                <div class="select-list" :class="{'sl-activate':isActivate}">
                    <div class="select-item" v-for="item in departments" :key="item.DepartmentId">
                        <i class="fas fa-check"></i>
                        <div class="select-item-text">{{item.DepartmentName}}</div>
                    </div>

嘗試如下代碼片段：

new Vue({
  el: '#demo',
  data() {
    return {
      positions: [{PositionId:1, PositionName:'ccc'}, {PositionId:2, PositionName:'ddd'}],
      departments: [{DepartmentId:1,DepartmentName: 'aaa'}, {DepartmentId:2,DepartmentName: 'bbb'}],
      isActivate: null,
    };
  },
  methods:{
    activateCbb(type) {
      if(this.isActivate === type) {
        this.isActivate = null
      } else {
        this.isActivate = type
      }
    },
  }
})

Vue.config.productionTip = false
Vue.config.devtools = false

.sl-activate {
  display: block;
}
.inactive {
  display: none;
}
