Hi,

I am trying to add a first and last name field to my mailing list/newsletter sign up form which ideally integrates with the customer section on Shopify.

I would like the first name and last name fields to be in a single row on desktop instead of being stacked on top of each other. On mobile I would stack them on top of each other.

Would anyone be open to helping? Thanks in advance!

Hi, @atmos-art

I can add the fields for your store. But it needs to add some custom code. If you need my help, please let me know.
