Is something like in the image below possible with Squarespace? I currently use a Form with drop down Menus for selecting Sweets to go into a Pick n Mix Bag but it would be a lot more user friendly to select actual images of the sweets so people know what they are? Thinking I may have to move to woo commerce or shopify which is such a shame as I love every other aspect for squarespace! Any help or tips would be really appreciated!
