Question

我正在使用Drupal8，我必须创建一个Web表单。问题是，我的名字和地址邮件会自动输入到条目中。我不希望这样。我正在搜索设置，但找不到我的名字，等等...

如何删除它们？

 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。

先谢谢您

塞西尔

Answer 1

请在您的module.theme（模块是您的主题名称）文件中使用带有表单ID的hook form_alter。请参阅此enter link description here
