如何从 Drupal 8 联系表单中的输入中删除默认值

Question

我正在使用 Drupal8，我必须创建一个网络表单。问题是我的姓名和地址邮件会自动放入条目中......我不想要这个。我正在设置中搜索，但找不到我的名字等...

我怎样才能删除它们？

 My webform :
    
    Full Name:
       Cecile
    
    Mail:
       cecile@jfdifjid.Fr

你知道我的意思吗？我想删除它并添加占位符。

提前谢谢你

塞西尔

请在你的module.theme（模块是你的主题名）文件中使用带有表单ID的钩子form_alter。 参考这个enter link description here
