I am working on a WordPress site based on Customized cakes. I am stuck with one element where the customer can make his own cake, i.e. can add Base, Toppings, Layers. Its like like PizzaHut or Dominos. where on-click of 1 topping its image will occur, on-click of 1 Base its image will occur and furthermore. I have done with HTML, JS where on-click I am able to change images of cake, but its all together a different element & this one is different. I am looking for code suggestion or any links which can be helpful to me. There is a plugin Gravity form but I am looking for other option. Here A customer can create his Cake by adding Base, Toppings, Layers.
The Visual Form Builder is an alternative to gravity https://de.wordpress.org/plugins/visual-form-builder/
