Integrations or custom code for product configurator

Hi guys, so i want to integrate a product configurator onto my e-commerce website. I will mainly need it to be used on a phone as 97% off my traffic is mobile. I have attached some images of how i want it to function, i just need a push in the right direction as i have no clue where to start and if i will need to write some custom code or if there is an integration that i can use or if it is even possible with webflow. Thanks in advance! Leo.

Here is my site Read-Only: (Webflow - K9GRILLZUK)
