These blocks can be added to any section that accepts theme blocks; blocks that belong to one section are described on that section’s page. | Block | What it does | | --------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------ | | [Button](/reference/blocks/button.md) | A link styled as a button or an arrow link. | | [Buy buttons](/reference/blocks/buy-buttons.md) | Quantity selector, add to bag button, dynamic checkout buttons and the gift card recipient form. | | [Collapsible row](/reference/blocks/accordion.md) | A collapsible row: a heading that opens to show the blocks inside it. | | [Compare](/reference/blocks/compare-button.md) | An "Add to compare" checkbox for product pages. | | [Complementary products](/reference/blocks/complementary-products.md) | "Pairs well with" products chosen in the Search & Discovery app. | | [Custom Liquid](/reference/blocks/custom-liquid.md) | Paste Liquid, HTML or an app embed code. | | [Description](/reference/blocks/product-description.md) | The product description from Shopify admin, with an optional heading and divider. | | [Divider](/reference/blocks/divider.md) | A horizontal line with adjustable spacing. | | [Email signup](/reference/blocks/email-signup.md) | A newsletter email field that adds subscribers to Shopify customers. | | [Follow on Shop](/reference/blocks/follow-on-shop.md) | A button that lets customers follow your store in the Shop app. | | [Group](/reference/blocks/group.md) | A container that stacks or lines up other blocks, optionally as a card or a link. | | [Heading](/reference/blocks/heading.md) | A heading with size, level, color, width and alignment. | | [Icon](/reference/blocks/icon.md) | An icon with a short label, for example delivery or returns promises. | | [Image](/reference/blocks/image.md) | An image with shape, corners, link, caption and optional zoom on hover. | | [Inventory status](/reference/blocks/product-inventory.md) | Stock status with low stock messages and delivery notes. | | [Menu](/reference/blocks/menu.md) | A heading and the links of a menu, in a column or a row. | | [Numbered step](/reference/blocks/numbered-step.md) | A numbered step with a heading and description. | | [Pickup availability](/reference/blocks/pickup-availability.md) | Shows stores where the selected variant can be picked up. | | [Price](/reference/blocks/product-price.md) | The price, with sale price, "From" pricing and tax notes. | | [Product card](/reference/blocks/product-card.md) | A product card that holds the card's blocks: media, title, price, vendor, rating, swatches, inventory and compare. | | [Product details line](/reference/blocks/product-meta.md) | A line with the vendor, rating and SKU. | | [Product title](/reference/blocks/product-title.md) | The product title, as the page heading or a card link. | | [Rating](/reference/blocks/product-rating.md) | Stars and review count from review app metafields. | | [Restock request](/reference/blocks/restock-request.md) | A form for sold-out variants that sends a restock request to the store by email. | | [Scale](/reference/blocks/rating-bar.md) | A labeled scale from 1 to 5, for example heat retention. | | [Share](/reference/blocks/share.md) | Share or copy a link to the page, as a button or an icon, inline or pinned top right. | | [Social media icons](/reference/blocks/social-links.md) | Links to your social profiles from Theme settings › Social media, as icons or names. | | [Spacer](/reference/blocks/spacer.md) | Empty space with separate heights for large and small screens. | | [Specification](/reference/blocks/spec-row.md) | One extra row in the specifications table. | | [Specifications](/reference/blocks/product-specs.md) | A specifications table from product options, vendor, type, weight, SKU and metafields. | | [Swatches](/reference/blocks/product-swatches.md) | Color swatches on product cards that preview and select a variant. | | [Text](/reference/blocks/text.md) | A paragraph of rich text with size, color, width and alignment. | | [Variant picker](/reference/blocks/variant-picker.md) | Option buttons, dropdowns and color swatches for choosing a variant. | | [Vendor](/reference/blocks/product-vendor.md) | The product's vendor, optionally linked to the vendor collection. | | [Video](/reference/blocks/video.md) | An uploaded video or a YouTube or Vimeo video. | | [Volume pricing](/reference/blocks/volume-pricing.md) | Quantity price breaks from B2B catalogs for eligible customers. |
