# Shopify Theme Glossary

Definitions of common terms used on shopinfo.app and across the Shopify theme ecosystem.

## Presets (Style Presets)

Pre-configured variations of a base theme with different color schemes, typography, layouts, or styling options. Presets allow merchants to start with a customized look without manual configuration.

## Theme Store ID

A unique numerical identifier assigned to each theme in the Shopify Theme Store. Used in theme URLs and for tracking themes across updates.

## Online Store 2.0 (OS 2.0)

Shopify's modern theme architecture introduced in 2021, featuring improved customization through sections and blocks throughout the entire store. OS 2.0 themes offer greater flexibility without code changes.

## Mega Menu

An advanced, multi-column dropdown navigation menu that displays multiple categories, subcategories, featured products, and promotional images all at once. Reduces clicks to purchase by showing the entire catalog structure.

## Quick View

A feature that allows customers to view key product details, images, variants, and add-to-cart functionality in a popup without leaving the collection page. Can reduce clicks to purchase by 40-50%.

## Sticky Header

A navigation header that remains fixed at the top of the screen as users scroll down the page. Ensures the main navigation menu, search bar, and shopping cart icon stay visible and accessible.

## Vintage Theme

Older themes built before Online Store 2.0 that use Shopify's previous theme architecture. While still functional, vintage themes have limited customization capabilities compared to OS 2.0 themes.
