Here is a mobile-friendly OpenCart template for a sunglasses shop. As an instrument for navigation, it features a mega menu with a semi-transparent drop-down panel. You can arrange all product categories and subcategories in columns on it and add a promo banner. Tabs allow customers to browse your inventory by new, special, best-selling, and popular items. Thanks to labels, new and discounted items catch an eye at once. What buyers will find comfortable is a possibility to shop by brands. They can also see the physical location of your shop on Google maps. Besides selling sunglasses, you can engage visitors with interesting posts on a regular basis. That's what blog integration is meant for.
