Form with a limit of entries

My Mautic version is: 2.15+
My PHP version is: 7.0.18

I would like to create a form with a limit of entries.

Example. The form can only accept 50 applications and then display any message, but will not allow you to accept new applications.

How to do it?

That sounds like a custom extension to Mautic. I’m not aware you could limit it currently with standard functionality.

I found something like this.

Limiter for Mautic

“This plugin disable Mautic features after extend limit of number of identified contacts. You can hide create new contact, new email, campaigns or editation too.”

I haven’t tested yet.
Is it for a specific campaign or a specific form?

Something new? Have any ideas?
