Html code question

Hello in html code in themes it has a FOR command to process fields


Is there a way to process or show only one of the fields (i.e change the position of invoice number only)?
thank you

Themes are not written in HTML. They are in Liquid. See the Guide: https://www.manager.io/guides/10368. You would need to include quite a bit of conditional logic and multiple for loops to pass through the fields array at least twice.
