I want to add a list after the product price ( something like : free shipping , made with love , etc ).
I couln`t find anything so i need some help!
I really like this idea and took a look at my own test store to see if I could find out how to do that. Part of the solution will be related to WHERE you want this to show (Homepage sections, product page, collection page, etc).
Please know that I am not a trained developer and any suggestions I make should only be tested after making a backup version of your theme for recovery. I am not able to reverse any theme code changes you attempt.
With that out of the way - If you want it to show across all price elements of your store then you should be able to add the desired text in the theme code next to the appropriate price section. Using the Dawn theme on my store I was able to open the code editor, navigate to the price.liquid file and add the desired text next to the standard price section. Which you can see in the screenshot below:
And once saved, it will add that additional text next to the regular product price across the whole store (Storefront, search, collection page, product page, etc):
I am not experienced enough to add this to just one specific section of your website. Hopefully this gives you a place to start though!
