Welcome to Theme Log!
Theme Log is a series where we share theme customizations, patterns, and cool Liquid tricks.
If you missed the previous topic, feel free to check it out here.
There has been a bit of a delay with these round-up topics. I was initially skipping them because I moved my family into a new home and needed the time for unpacking. Then I wanted to let Shopify Editions Summer '25 and the Editions.dev event to take priority instead. The unpacking part has taken a bit longer than expected because I also decided to expand our front garden, helped my FIL move, and have been preparing to welcome our 3rd child to the family early next week!
I mentioned last time about figuring out a better format for these starter posts and I came to the conclusion that I should set them up as a monthly round-up where we can share things we had the opportunity to work on throughout the entire month.
That said, for the month of July 2025, let’s set this round-up for specific customizations where you utilized updates shared with the recent Shopify Editions Summer '25.
Did you work with Horizon? Generate blocks with AI? Maybe it was adding a discount code input to a cart drawer. Whatever it was, please share it with the community!
Note, I also have another endeavor for the community that I started working on while I was away and will be sharing more on that soon!
I am looking forward to seeing what everyone shares this month!
Got a trick? Did you build something cool?
If you have done something cool with any Online Store 2.0 theme, reply below with a snippet or a screenshot. Bonus points for sharing reusable code blocks!
