How to add loop statement in email template for Odoo 14

Question

I'm trying to print some values in the body HTML of an email template based on the values in the environment context object (ctx object). Unfortunately, non of the syntaxes mentioned in the forum or in the Jinja documentation itself is not working, and I get the "Email template does not fit the required schema !" error in the log.

I'll be grateful for any clue or solution to this problem.

% endif
% endfor
Another example from Odoo code using ctx [1] . (Check line 91 a
