I’m using the Impulse theme and am trying to add the Hear About Us snippet in my checkout page as a required entry with a drop down menu with customised options. I’ve been trying to do this via the help centre - have successfully added the hear-from-us code in Snippets in Themes but can’t seem to insert the next bit of code as I don;t seem to have cart-template.liquid or cart.liquid in my Sections at all.
