When you build a product with components such as Parts, Texts or Logos, each of these components, or layers, are stacked on top of each other like sheets of acetate.
Value options have no visual effect on the product preview and can be positioned anywhere in the component list.
Editing the position of a layer
You can edit the position of a layer by dragging and dropping it up or down the list. A layer that is located on of top of your components list will appear on top of your product.
Make sure to position your texts and logos on top our your component list to prevent them from being hidden behind other parts of your product.
