一、动态列表

动态列表Form.List是包含多个表单的情况，往往是多维数组数据，意思就是往往这个数据传递到后端是数组数据。

二、场景实现

实现效果

实现代码

import React from "react";
import _ from "lodash";
import "./index.less";
import { PlusCircleOutlined, CloseCircleFilled } from "@ant-design/icons";
import { Typography, Form, Input, Select, Space, Button } from "antd";

const App = () => {
  const [form] = Form.useForm();

  const onFinish = async () => {
    const values = await form.validateFields();
    console.log("Received values of form:", values);
  };

  return (
    <Form
      form={form}
      layout="vertical"
      name="dynamic_form_nest_item"
      onFinish={onFinish}
      autoComplete="off"
    >
      <Form.Item label="商品资源">
        <Form.List name={"source"}>
          {(fields, { add, remove }, { errors }) => (
            <>
              {fields.map((field) => (
                <div className="source-list-item" key={field.key}>
                  <Space align="baseline">
                    <Form.Item
                      label="商品类别"
                      validateTrigger="onBlur"

                              ? Promise.reject("请选择商品类别")
