[login to view URL] Here is the description of the app taken from the url: "Make, Model, Year Search Bar Provide your customers the ability to quickly and conveniently search your store, for the products they seek. Configurable to display in Year, Make, Model order. Persistent Vehicle Filtering Vehicle selection is saved, and persists throughout the browsing session. This allows collections to only show compatible products, without requiring customers to re-select vehicle filters on every page. Manage Vehicles & Product Mappings Quickly add vehicles, and create product mappings. Add any number of Makes, Models, and Years. Assign up to 1,000 vehicle mappings per product. Mappings work by leveraging Shopify Product Tags. Spreadsheet Import Use Excel Upload, to import vehicles and assign product mappings. Suitable for imports of any size, and works great for larger jobs. My Garage Customers can save vehicles to their account, for quick and convenient return searches. Theme Integration Add to your existing theme, by adding a small code snippet to your liquid template. The automotive search bar design can be modified, by editing liquid HTML and/or CSS. Advanced Supported Features The following optional features are compatible with our app: Filtered Collections (only displaying categories which match vehicle selection) Verify fitment and display vehicle label on product page Filter vehicle product results by brand, tags, type, and more. *Each Advanced Supported Feature listed above requires specific theme modifications. We provide instructions on implementing some of these features in our documentation. If needed, we can assist with these features and other custom development requests, at our standard development rate. Contact us for more details." Thank you for applying.
