Custom Liquid block

Applies to: Combine 4.2.0 and later. Added in: Combine 3.1.0. Last checked: 2026-10-13 against Combine 4.2.0.

The Custom Liquid block runs your own Liquid or HTML code inside a slide, card or column of a flex section. Use it for an app snippet, a metafield value or a small embed that no other block shows.

Where to find it: in a Flex slideshow, Flex grid, Flex cards or Flex columns section, select Add block inside a slide, card or column, then choose Custom Liquid.

Adding your codeCopy Anchor Link

• Paste the code into Custom Liquid. Liquid objects such as shop, product (on product pages) and metafields work as in a theme file.
• The block shows nothing while Custom Liquid is empty.
• The code sits in the card's text column, between the other blocks, and moves with them when you drag it.

When should I use the Custom HTML / Liquid section instead?Copy Anchor Link

When the code needs a full-width area of its own. The Custom HTML / Liquid section can go anywhere on a page, while the Custom Liquid block lives inside a flex section card, next to its headings and buttons.

Why does my code show nothing on the storefront?Copy Anchor Link

The code outputs nothing on that page, or a script waits for an event that has already fired. Test the code in the theme editor preview and in a browser console. For help with the code itself, see Custom work and code changes.
