求助：如何为多折叠区块添加独立运行的表单（附代码）

数据老陈

实现折叠区块的独立表单（可扩展）
以下是修改后的代码，已完成logo和mascota两个独立可运行的表单，代码结构清晰，方便你复制扩展第三个web区块的表单：
关键修改点

每个表单使用唯一ID（form-logo、form-mascota），避免全局ID冲突
修正了原代码中表单内radio与外层区块ID重复的问题（比如将radio的id改为service-logo）
编写了通用的表单提交处理函数，每个表单绑定独立的提交逻辑，无需重复写JS代码
保留了你原有的折叠显示/隐藏逻辑，表单仅在对应区块展开时显示

扩展说明

要添加第三个web表单，只需：
复制logo区块的表单代码到web的div#web中
将表单ID改为form-web
将表单内的字段ID后缀改为-web（比如nombre-web）
在JS中添加一行handleFormSubmit('form-web');
