element-plus 使用checkbox标签无法选中

Question

vue3.0+element-plus 使用el-checkbox-group无法选中
代码：

   <el-form-item label="口味：" label-width="120px" prop="dishTaste">
          <el-checkbox-group v-model="chooseTasteList" @change="chooseTaste">

              <el-checkbox v-model="tasteList.id"
                           v-for="(tasteList,tasteListndex) in getInitializeData.getTasteList"
                           :key="tasteListndex"
                           :label="tasteList.tasteName"
                           size="large"></el-checkbox>

          </el-checkbox-group>


        </el-form-item>

这个是有默认选项，但是选择其他的无法选中，这是哪里出问题了
效果如下图

而且默认选中的这个无法取消，咋解决这个

Answer 1

把 v-model="tasteList.id" 去掉

Answer 2

你只需要 一个 v-model就行 ，el-checkbox 的去掉
示例里有

Answer 3

应该是你chooseTaste这个方法有问题，你贴下代码

    <el-checkbox v-for="city in cities" :label="city" :key="city">{{city}}</el-checkbox>
  </el-checkbox-group>
</template>
<script>

    methods: {
      handleCheckAllChange(val) {
        this.checkedCities = val ? cityOptions : [];
        this.isIndeterminate = false;
      },
      handleCheckedCitiesChange(value) {
        let checkedCount = value.length;
        this.checkAll = checkedCount === this.cities.length;
        this.isIndeterminate = checkedCount > 0 && checkedCount < this.cities.length;
      }
    }
  };
