Hello Everyone, How we can add the '*Best Seller Product*' section on the homepage of Web Store Suite Commerce using Extension Configuration?

Simply create the Merchandizing rule and add it to home page via SMT

@Mohammad Sharaf Ali how we can align the merchandise ruled items into the horizontal? I did not found the exact template file?

You need to create custom merch zone .txt file for that purpose. I suggest you to go through SuiteAnswers first to grab all the info you need regarding merch zone customization.

Sure, Thanks
