列表数据

const ymList = ref([
  {
    ym: "茯苓",
  },
  {

<el-dialog
      v-model="ymDialogVisible"
      title="请选择"
      draggable
      width="60%"
      destroy-on-close
      center
    >
      <div class="row">
        <div
          class="ymdiv"
          @click="ymClick(item, index)"
          v-for="(item, index) in ymList"
          :key="index"
        >
          {{ item.ym }}
          <el-icon color="#FF0000" v-if="item.click"><Select /></el-icon>
        </div>
      </div>
      <template #footer>
        <span class="dialog-footer">
          <el-button @click="ymDialogVisible = false">取 消</el-button>
          <el-button type="primary" @click="ymconfirm">确 定</el-button>
        </span>
      </template>
    </el-dialog>

点击事件

//点击多选操作
function ymClick(item, index) {
  item.click = !item.click;
}
//赋值到表单操作 需要定义 kftjForm.value.jtzc=[]
function ymconfirm() {
  kftjForm.value.jtzc = ymList.value
    .filter((item) => item.click)
    .map((item) => item.ym)
    .join("、");
  ymDialogVisible.value = false;
}

css样式

  display: flex;
  margin-bottom: 5px;
