If you want to improve the user experience on your Drupal Commerce website, providing a product comparison feature can significantly help customers compare different products. This feature enables users to compare the features, specifications, and prices of different products, which can help them make more informed purchasing decisions. In this article, we will discuss the steps to implement a product comparison feature in Drupal Commerce.

Step 1: Install the Drupal Commerce Module

Before we dive into the implementation of the product comparison feature, you need to have Drupal Commerce installed on your website. Drupal Commerce is a popular e-commerce solution that provides a flexible and customizable platform for building online stores. You can download and install the Drupal Commerce module from the Drupal website or via the Composer command.

Step 2: Select a Product Comparison Module

The next step is to choose a product comparison module that fits your requirements. Some popular product comparison modules for Drupal Commerce include:

  • Commerce Compare Products: This module provides a simple and efficient way to compare products on your Drupal Commerce website. It supports various comparison modes, including side-by-side and tabular layouts.

  • Commerce Product Comparison: This module enables users to compare multiple products on a single page. It provides a drag-and-drop interface that allows users to arrange the products in any order.

  • Commerce Feeds Product Compare: This module uses the Feeds module to import data from external sources, such as CSV or XML files. It provides an intuitive interface for mapping the product fields and colors to the corresponding fields.

Step 3: Configure the Product Comparison Module

Once you have selected a product comparison module, you need to configure it to work with Drupal Commerce. This involves setting up the module’s settings, adding fields to the product entity, and configuring the comparison layout and styling.

Most product comparison modules require you to add custom fields to your product entity. These fields should include product attributes such as price, dimensions, weight, color, and other relevant information. You should also configure the comparison layout and styling to match the design of your website.

Step 4: Add the Product Comparison Widget to the Product Display Page

After configuring the product comparison module, the next step is to add the product comparison widget to the product display page. This widget provides users with a button or link to add the product to the comparison list. Depending on the module you chose, the widget may appear in different locations, such as the product teaser or the product detail page.

Step 5: Allow Users to Compare Products

Finally, you need to allow users to compare products by accessing the comparison page. Depending on the module you chose, this page may show the products in a side-by-side or tabular layout, and it may also allow users to filter or sort the products by different criteria.

You can also customize the comparison page to include additional features, such as product ratings, reviews, or social media sharing buttons. This can further enhance the user experience and help users make more informed purchasing decisions.


Implementing a product comparison feature in Drupal Commerce can significantly improve the user experience and help users make better purchasing decisions. By following the steps outlined above, you can select and configure a product comparison module, add the comparison widget to the product display page, and allow users to compare products on a dedicated comparison page. With this feature, you can provide your customers with a powerful buying tool that can help them find the right product for their needs.
