Thank you so much Swean for the above solution. I went through my code and in few sections presets were missing, when I added I was able to see them in the list.
I am new to Shopify and trying to learn. can you give me a link to learn more about the structure of presets?
Topic summary
Newly created Shopify sections were not appearing in the Theme Editor’s Add section library, despite having 22 uniquely named sections and prior functionality a day earlier.
-
Initial checks suggested cache/browser refresh and reviewing Online Store > Themes > Customize to confirm section settings, plus verifying unique section names.
-
After the site URL and password were shared, deeper backend verification wasn’t possible, but the key recommendation was to check each section’s preset in the section schema.
-
Root cause: several sections were missing presets (the schema “presets” entry that allows a section to appear in the library). Once presets were added, the sections became visible.
-
A reference screenshot of presets was shared to illustrate what to look for.
-
Learning resources provided: Shopify section schema/presets documentation, Liquid objects reference, and the Shopify YouTube channel for further study.
Status: Resolved. Key takeaway: ensure each custom section includes a valid presets configuration so it shows up in the Theme Editor’s library.
