In WordPress, WooCommerce-based websites integrate this product filter in the search system using the plugin. WooCommerce enables this product filter functionality with an extension that is not free.

Most eCommerce websites rely on the search form system for their customers to find their product. As the online shop expands over time, so will the number of products. There will also be more product variations and different attributes for the users to browse. A simple search system will no longer be effective when an online shop is growing bigger by scale.
A product search filter plugin has some elements and functionalities that will give a direct impact on the user experience of the customers when they browse the product they want to purchase. Customers or users can browse products by different filter types, for instance by category, product title, or by price, and using filter elements such as price range sliders, checkboxes, or labels.

There are many WooCommerce product filter plugins that you can find and choose in the WordPress plugin directory. In this article section, we break down the essential components that you need to pay attention to before you decide to use the WooCommerce search filter plugin.
1. Filter Types
A product filter plugin would do best if it could handle different product filters. Some plugins will limit this option on their free version, but the basic search filters are usually filtered by category, tags, attributes, metadata, and by price.
Depending on how specific the search filter plugin that you would need, however here is a list of what the plugins are commonly able to filter the product by:
Category

Attributes (size, weight, flavors, etc.)
Taxonomies

2. AJAX Compatible
Why is AJAX often used in search filtering? This is mainly because it allows your consumers to obtain real-time search results as they type. So it’s quite important if you choose an AJAX compatible search filter plugin.
AJAX employs Asynchronous JavaScript and XML. AJAX is a technology that is built on a few programming languages. It allows you to rapidly search and show the content you require without having to refresh the page
3. Filter UI / UX Elements
The filter UI / UX elements play an important role in search filtering as this would give a direct impact on the user experience and how they control the search filtering on your eCommerce website. Hence, a successful search filter plugin should have a good design of UI/ UX elements.
An active filter display would be handy to track the filter types that have been running or processed. A user can adjust or refine the search accordingly by deleting the active filters and starting another search or even pressing the reset button to delete all the active filters.
In some cases, a toggle button or icon to hide and show the search filter or sorting would help to declutter a shop landing page. Especially if there are many numbers of search filters and sorting elements to include.
Here is a list of search elements that you might find in the WooCommerce product filter plugin:
Radio buttons
Dropdowns
Range slider
Select buttons/ labels
Multi-select
4. Sorting Configuration
By default, WooCommerce provides a sorting system for the products on the shop page. Nevertheless, some product filter plugins also include a built-in customizable sorting system which is often better than the default system has offered.
The integrated sorting system would enhance the search filter performance since you can customize the settings to fit your requirement especially if you have unique products. A good sorting system makes the search result and helps the users to find and decide which products they would like to purchase. It’s fairly important to have this feature optimized if the product filter plugin you’ve chosen provides it.
5. Filter Position
A product filter plugin might have a setting for you to configure the filter position. The common position for the search filter section is at the top of the product search result or at the sidebar area of your shop product page.
6. Integration
It’s very often that you would integrate a product filter plugin using the WooCommerce sidebar widget. The second option is to add a shortcode to integrate the search filter on your shop page. A few plugins would give you instant integration without you having to add a widget or shortcode.
7. Mobile Friendly Design
The product filter plugin must be responsive or mobile-friendly in design. Online shoppers may access your eCommerce website from different devices with different screens. So it will be helpful to have a configuration setting on the product filter plugin to make sure the filter element can be accessible on many types of devices.
