STMB Mega Nav

Build, organize, and publish a custom storefront navigation header for your Shopify theme.

• Visual menu builder. Create nested product and link categories with guarded tree editing.
• Storefront-ready data. Publish the default nav to Shopify app-data metafields for initial Liquid rendering.
• Theme app extension. Render the custom header from the published menu data without late client-side link creation.
