SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Shoppers comparing multiple products often open separate tabs and manually cross-check specifications, which causes drop-off before purchase. This Skill guides the implementation of a side-by-side product comparison feature with a floating selection tray, grouped attribute tables, and shareable URL state. ## Core Features & Use Cases - Platform-Specific Setup: Step-by-step configuration for Shopify (Comparify app), WooCommerce (YITH Compare), BigCommerce (built-in Cornerstone comparison), and custom/headless builds. - Comparison Tray and Table Components: React components for a floating comparison tray with placeholder slots and a sticky-header table with difference highlighting and a show-differences-only toggle. - URL-Synced State: Selection state stored in the URL via replaceState so comparisons can be shared or bookmarked without polluting browser history. - Use Case: An electronics retailer adds Compare checkboxes to camera listing pages; shoppers select up to 4 models and view a grouped spec table where differing rows are highlighted and identical rows can be hidden. ## Quick Start Use the product-comparison skill to build a side-by-side comparison table with a floating selection tray for my Shopify or custom storefront.

Frequently Asked Questions about product-comparison

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add a product comparison feature to my Shopify store?▼

Shopify has no built-in comparison, so install an app like Comparify or Product Compare from the App Store. Configure which product metafields appear as comparison rows, and the app adds Compare checkboxes to product cards plus a full comparison table page.

How to build a product comparison table in React?▼

Build a table component accepting products, attributeGroups, and showOnlyDifferences props, rendering grouped attribute rows with sticky headers. Store selected product IDs in the URL with URLSearchParams and history.replaceState so comparisons are shareable without breaking back-button behavior.

Does WooCommerce support product comparison natively?▼

WooCommerce does not include comparison by default, but the free YITH WooCommerce Compare plugin adds it. It uses WooCommerce product attributes as table rows, supports a show-differences toggle, and adds Compare buttons to shop and archive pages.

Why does my comparison table break on mobile screens?▼

Comparison tables overflow on small screens when columns are squeezed instead of scrolled. Wrap the table in a container with overflow-x: auto, set a min-width on the table, and use position: sticky with left: 0 for the attribute label column.

How many products should a comparison table support?▼

Limit comparison to 2-4 products, since more than four columns breaks table layout on most screens. Enforce the cap in the UI by disabling Compare checkboxes once the maximum selection is reached.

How do I handle products with missing attributes in a comparison table?▼

Normalize the union of all attribute keys across compared products and represent missing values as null, rendering them as N/A. Never skip the cell, because omitted cells misalign table columns.
