This is an accepted solution.
Goto Online Store-> Themes - > Action dropdown -> Edit code -> Goto Snipptes folder -> click on product-grid-item.liquid
See screenshot below. Change for the small device ( for mobile ) small--one-half. If "small--one-" already then replace it with "small--one-half"
Hope this works.
Your solution worked great. Thanks a lot.
I had one more question;
If we wanted to display the items of the collection as a carousel, is it possible? Right now we have only two options grid & Collage. Is carousel possible for the home page of brooklyn?
Yes, this is possible to display in the carousel but It would need customization to implement the carousel for the products, Unfortunately, there is no simple solution otherwise I will be happy to help you.
I would suggest hiring a Shopify expert to assist you OR feel free to contact me.
