Validating fields in a form template?

Question

MODX

Help pliz.
I have a form that is processed by Formit. In general, the order form is very large and there are a lot of fields. I set everything up, everything comes, but there are also optional fields. And I need to make it so that if a person has not filled in the field, then do not send it to the mail. That is, for example, there is such a field in the template:
Name:
It is not mandatory, and when the user does not fill in, I want him not to send such content to the soap "Name:" Maybe through If as- then?
I hope at least somehow explained at 3 o'clock in the morning: D
Thanks
