On the product page, you can configure the characteristics that will change when you switch between variants.
For example, for a T-shirt, the sleeve length is displayed, which changes depending on the size you select.
How to set up
Create the necessary attributes of the Variants group in the product template.
Select the attributes that will be used to switch modifications on the product page.
Fill in the values of these attributes for the products manually or using import.
Go to the Website → Pages section and open the settings for the corresponding catalog category.
In the Attributes on the product page section, check all the options you want to see in the Features block on the product page. Save your changes.
After you make these settings, when you switch modifications, for example, by the Size attribute, the values in the Features block will change to the appropriate value for the selected size.
