Need to choose what fields are mandatory in the forms...

Would it be possible to choose which mandatory fields we want to have in our forms ?

The phone number is added in my Lead magnet form… but as it is not mandatory, people do not fill it. On the same way, they put only their first name.

I would like to avoid the curious and competitors (this way is eady for them) and have only the most motivated people, those who are really interested by my ebook.

I prefer to have less but better qualifyied!

Thanks in advance.
