You need to use rich list rather than Multi line as this supports a lot of formating
Topic summary
Goal: show bullet-point lists from product metafields inside collapsible tabs, instead of comma-separated text.
-
Option 1 (theme code): Loop a multi-line metafield in Liquid and render each value as a separate line with a leading dash. Example provided and placed in main-product.liquid (Dawn). Screenshots illustrate placement. This avoids commas by controlling output via code.
-
Option 2 (data formatting): Use a Rich Text (referred to as “rich list”) metafield type instead of Multi line, which supports formatting. Directly typing list HTML (
- /
- ) or bullet-styled lines can display as bullets.
-
Limitations noted: Plain multiline metafields don’t support HTML; attempting to paste HTML shows raw code. Rich Text works when entered manually, but copying from Excel or importing via Matrixify causes HTML to disappear, breaking bullets.
Status: Partial resolution. Bullet lists can be achieved either by Liquid looping of multi-line values or by using a Rich Text metafield with manual entry. Open issue remains on preserving bullet formatting during bulk import (Matrixify) or paste-from-Excel workflows; no confirmed workaround provided.
