Fields with 0 input not to appear in the email

Hello @zuccherato,

My apologies, I have only now seen your ticket, however, I think I have answered a similar question in another of your support threads.

In the e-mail and thank-you pages, it is possible to check if the field has a value or not using the if_not_empty expression in the tags, or if some fields are shown, based on the value in a specific field, with the block and endblock expressions, for example:

<% Field name1 if_not_empty%>

and

<% Fieldname2_block%>
<% Fieldname3 separator = {{:}} after = {{br>}}%>
<% Fieldname4 separator = {{:}} after = {{br>}}%>
<% Fieldname2_endblock%>

Best regards.
