Hi, I'm new to HikaShop (Essentials) and still learning a lot about it. One thing I thought I could do but cant quite figure out. I need to be able to sell a product at a certain price. I need to have multiple options/add ons defined. Each would have a qty of its own and the product price would increase or decrease accordingly. I would need to have multiple options like this.

An example would be a telescope. The scope would cost $200. The buyer can then select from multiple eyepieces and adapters all at different prices. However, I only want certain adapters to be available if certain eyepieces are selected. The buyer could select multiple quantities of each eyepiece or adapter.

Is this possible? If so do I use options, characteristics, customs fields? Any help would be great.
