Use dynamics fields in Google Form

[vincenzom_cp]

Hi! I have a question about google form.
I'm creating a form where I would like to insert dynamic fields, let me explain.
I would like these fields to be shown or hidden dynamically and made mandatory based on a condition. I don't want to use conditional sections. In short, I would like to create a structure similar to the one in the following example:
Field when I choose "SI"

field when i choose "SI"

Field when I choose "NO"

field when i choose "No"

Is there any way to accomplish this? Maybe with an add-on?

Thank you so much!
