How can I sort products appear in alphabetical order?

Hi,

When configuring your product listings, you have a dropdown named "Ordering field", where you should select "product_name" and save.

For existing product listings, you'll get there via the HikaShop backend -> Display -> Content menus (or modules), then click and open the one in question, and look at the pane "Parameters for products". It's right at the top there.
