如何从在Drupal 8的接触形式输入删除默认值

Question

我与Drupal8工作，我必须创建一个Web窗体。问题是，我的名字和我的ADRESS的邮件会被自动放入entries..and我不希望这样。我在寻找的设置，但我不觉得我的名字等..

我怎么能删除？

 My webform :

    Full Name:
       Cecile

    Mail:
       [email protected]

你知道我的意思吗？我想删除，并添加占位符。

先感谢您

Answer 1

请使用与您的module.theme表单ID挂钩form_alter（模块是你THEMENAME）文件。请参阅本enter link description here

我不知道该怎么用这个钩子做：
