First, click the “+ADD” button to add:
GROUP LAYER – you can rename it depending on your product, if you are creating a sunglasses for example then you can create a group with the name “Lens”, “Frame”, “Arms” etc..
Second, click the “+” button on the right side of your group layer to add:
PARENT LAYER – you can also rename it and let’s use again as an example is sunglasses. If you are creating Sunglasses and your first group is Lens then you can put layers like Black, Blue, Amber, Brown etc.. (you can choose frame styles here)
Third, click again the “+” button on the right side of your new parent layer to add:
CHILD LAYER – you can also rename it and if you have such a product then you can add child into your Parent Layer. But this layer is lease use since the Parent Layer can simply work without the Child Layer.
