HTML Form required parameter

[Marco_Co]

Hi Guys,

I have created a form on an CMS page. This form posts the Input to our API where all the input data is processed. All this works good but I have a simple problem. In my form are required fields. I tried it this way

 

<form action="#" method="post">
  <input type="text" name="firstname" required>
  <input type="submit" value="Submit">
</form>

 

But after saving the required  is removed. So after this I tried this steps

but that did not help.

 

What can I do to make this fields required?

Probably not a simple question
