The vehicle is stored in the customer's session while browsing your store(s). The vehicle that is selected is clearly displayed at all times. When the customer does a search for a vehicle, their vehicle selection is stored. As they click from page to page, or category to category - the vehicle selection "sticks". The customer can easily change or clear their vehicle selection at any time from any page.
Will hide options that do not have product. Will only show Makes/Models/Years that will yield matched product results. Keeps dropdowns clean and concise which avoids losing or confusing the customers.
The user can make a partial selection. So if they do not know the engine, or trim, they can ask to see all products matching a given make/model. In that case, all engines, or all years (or whatever levels you have setup) will be used for filtering. The labels can be changed to "All Makes", "All Models", "All Years" to make the behavior apparent to the user.
The vehicle applications you add to your products can be listed out on the product page if you desire. This is useful for Automotive B2B where someone reselling your products just wants to see the automotive applications for a product. It is also useful for your regular customers.
If a user clicks a category they're going to see a bunch of products that don't "fit". For certain categories you want the user to see products only once they enter their vehicle. This can be turned on and off on a category by category basis, and the template file that the user is shown for the splash page is fully customizable. Once the user enters their vehicle they will be shown the matching products.
You can optionally include a 'category chooser' to allow the user to search parts that fit their vehicle from a specific category. You may choose to have "all" as the first option to search all categories, or you may disable the category chooser which will cause it to search all categories by default. You can easily control which categories to display, if at all, and how they are presented to your customer.
You can run in either AJAX or OFFLINE mode. The difference is Offline mode will give a smoother experience. AJAX mode will keep your actual page size down.
Choose to show/hide the search filter from specific categories. In this way you may only have a single automotive category. Or maybe you have all automotive categories except a few.
