How to replace preset files
Important Note:
When replacing preset files, it's better to work with a duplicated theme. By making a copy, you create a safeguard: if something goes wrong with the files or if you make an error, you can always create a new copy.
However, if you perform these actions on the original theme, you won’t be able to restore it to its previous state.
Once everything is verified and works correctly in your copied theme, you can publish it and set it as the main theme.
Edit Code Instructions
To apply preset files, click on the “Three dots” icon and select Edit Code.
On the Edit Code page, open the Templates and Sections folders to replace the necessary files in your theme. This will apply the preset style you want.
