title: WordPress Customise Form
body: <p>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 &amp; 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.</p>
