Description
Comet LevelUp for WooCommerce is a high-performance conversion and polish suite for WooCommerce stores. It upgrades your single product pages, checkout flows, and catalog browsing without heavy page builders or slow third-party scripts.
Built with modern PSR-4 Object-Oriented PHP and Vanilla JavaScript, Comet LevelUp adds zero frontend bloat. Features are modular and lazy-loaded only when enabled.
🛍️ High-Converting Product Galleries
- Modern Gallery Layouts: Choose from Bottom Carousel, Left Thumbnails (Nike Style with sticky rail + floating index pill), Dual Grid (Nike Classic), Apple Showcase (frosted glass pill dots), Editorial Mosaic (Farfetch/SSENSE asymmetric magazine spread), Filmstrip Scroll (Lululemon horizontal snap + live progress bar), Right Thumbnails, Vertical Stack (Zara style), and Hero + Mosaic (Gymshark style).
- Aspect Ratio Control: Maintain uniform image aspect ratios (1:1, 4:5, 3:4, 16:9, or natural) across your entire catalog.
- Built-in Lightbox & Deep Zoom: High-resolution image zoom and smooth fullscreen lightbox without extra jQuery libraries.
- Product Video Embeds: Seamlessly display self-hosted and streaming product videos alongside photos.
- Sticky Product Summary: Keeps product title, pricing, and Add to Cart visible as users scroll long image galleries.
💳 Frictionless Cart & Checkout
- Auto-Update Cart on Quantity Change: Eliminates the outdated “Update Cart” button by updating totals dynamically via AJAX.
- Remove Zero Quantity Items: Automatically cleans up zeroed-out line items on cart adjustments.
- Hide Shipping When Free: Automatically conceals paid shipping options when Free Shipping criteria are satisfied.
- Instant Buy Now Button: Direct 1-click checkout bypassing the cart step.
- Uncheck “Ship to a Different Address” by Default: Reduces checkout friction and form clutter.
⚡ Catalog Polish & Store Speed
- Equalize Card Heights: Aligns shop grid cards neatly across fluctuating title lengths and imagery.
- Catalog Mode: Switch your store to a view-only catalog with a single toggle when needed.

FAQ
-
Does Comet LevelUp add frontend bloat or slow down my store?
-
No. Comet LevelUp is strictly engineered with modern PSR-4 PHP and pure Vanilla JavaScript. It uses zero jQuery on the front-end, no bulky third-party slider libraries (no Slick, no Swiper), and all modules are lazy-loaded only when explicitly enabled in settings.
-
Will this conflict with Elementor or other page builders?
-
No. Comet LevelUp includes an intelligent Builder Protection Boundary (
is_builder_or_admin()). When an Elementor editor or preview session is detected (elementor-preview), or within the WordPress Customizer, the plugin automatically yields and preserves native builder templates. -
Is Comet LevelUp compatible with WooCommerce HPOS (High-Performance Order Storage)?
-
Yes! Comet LevelUp explicitly declares compatibility with WooCommerce HPOS (Custom Order Tables) and Cart/Checkout Blocks via
Automattic\WooCommerce\Utilities\FeaturesUtil. -
How does the Aspect Ratio Lock eliminate Cumulative Layout Shift (CLS)?
-
Core Web Vitals often suffer when high-resolution images load and push down surrounding content. Comet LevelUp pre-allocates CSS container aspect ratios (such as 1:1 square, 4:5 portrait, or 16:9 landscape) with
object-fit: cover, ensuring zero visual jumping as images stream in. -
Can I bypass Comet LevelUp for debugging?
-
Yes! You can append
?disable-comet-levelupor?comet-levelup=offto any front-end URL to temporarily bypass LevelUp’s modules and inspect native WooCommerce behavior.
