Hello, @MAHDAR,
1. If you intend to use the default filter widgets of WooCommerce (Filter Products by Attribute widget), you will only be able to view filters for those categories where products have these attributes.
2. To achieve the desired result of having the Wishlist and Compare buttons on the same line, as seen in the demo, please follow the instructions below.
For the Wishlist button, navigate to Dashboard > XStore > Theme Settings > WooCommerce (Shop) > Single Product Page > Wishlist > Position and set it as After add to cart. For a better reference, please see the image here: https://ibb.co/0rYsgqW
For the Compare button, navigate to Dashboard > XStore > Theme Settings > WooCommerce (Shop) > Single Product Page > Compare > Position and set it as After add to cart. For a better reference, please see the image here: https://ibb.co/wMSDML1
3. Could you please provide a screenshot of the promotional text where you would like to add the custom icon so that we can review it and provide assistance accordingly?
Best Regards,
8Theme’s Team
