Hello,
To display the Package Size on your product page as shown in the demo, you’ll need to use WooCommerce’s product attributes feature.
First, go to Products > Attributes in your WordPress dashboard and create a new attribute called “Package Size“. Once added, click on “Configure terms” and create terms like 1000ml, 700ml, and 500ml.
After that, edit the product where you want to display the package size, scroll down to the Product Data section, and open the Attributes tab. Select the “Package Size” attribute, add the relevant terms, and make sure to check the option “Visible on the product page” before saving. This will display the package size as shown in the WoodMart demo.
