Extra features for a Shopify landingpage

Hi,
I need some extra features for one of may pages on shopify. Im running a poster store.

I need to be able to create a feature that enables me to a change the background color of and images, so a user would be able to chose between 5-6 diffrent background colors for a poster.. They should also be able to chose between 5-6 diffrent layouts for the poster(text on top of the background) and all of this should be updated live on the product page.

Besides this I have had some other featues tailor made for my shop which allows me to add more drop down boxes and input fields, which also needs to be compatible with the solution

I have found another site that has much alike what i want, and maybe we can use this as reference.. The site is called https://byfrank.dk/foedselstavle/
