Custom Liquid & Apps
The ultimate tool for advanced users. Inject raw Liquid code, HTML, or third-party app blocks directly into your store layout.
Custom Section (Apps)
Sellzar includes a dedicated Custom Section (Apps)template that can be added to any page. This section acts as a universal container for external content.
App Blocks (@app)
Use this block to drag-and-drop third-party Shopify App widgets (like review stars, trust seals, or chat bots) anywhere within the section.
Custom Liquid
Paste raw Liquid code or HTML directly. Perfect for adding custom scripts, tracking pixels, or unique UI components.
Design & Layout
Container Width
Choose between Page Width (centered) orFull Width (edge-to-edge) for your custom content.
Background Image
Optionally set a background image or color for the custom section to make your app widgets blend seamlessly with the store design.
Advanced Usage Only
Improper Liquid code can break your store's layout. Always test your custom code in a Theme Preview before publishing it to your live store.
