what does the 'depend' key word mean?

Question

I see in the admin panel this code {{depend prefix}} {{/depend}}:

What does it mean?

Answer 1

The {{depend}} condition checks whether there is data for the variable to output.

For instance: If the customer hasn't entered any prefix details then there will be no data in the database. The {{depend}} condition recognizes this and makes sure that in this case the prefix variable isn't displayed in the email template.
