Hi, looking for a way to change how many products are displayed horizontally. Currently be default 2, looking to increase this to 3 or 4.
This will need a developer to change your website template files. It's relatively simple to change to 3 or 4 columns, but the bigger challenge can be how it affects the overall design of the site. For example, you have fairly long product names so with 4 columns that will start to wrap to many lines. There also won't be much space for the price and other buttons. You also need to consider how it will render on all kinds of different devices and screen sizes. Sometimes what you are seeing is simply a compromise so it works at other resolutions.
I'd suggest finding an experienced developer and talking to them about how you want your product thumbs to look, rather than just jamming them into the 4 columns and leaving it a bit mangled.
