Is there a way to display sizes for products in the homepage or do you need to work with the tpl?
If you refer to sizes as being image thumbnails please follow → Thumbnails — CS-Cart 4.17.x documentation
also the size depend on the columns, more columns less width
if you are talking about product sizes, first create the product sizes as options, and then add the option group to the product tab and it will be displayed/selectable at checkout.
Thanks for the reply. Not the image sizes but displaying the size of a product like shoes size 10.
