Only show accessories

We want to show accessories, only when a main product is selected. But, we also need an ordertype, that allows to order ONLY accessories !

follow these steps :

1. Make new Product Categories : Accessories – bags

2. Set this new category ( with 'Accessories _ ' in front of it) as ‘Accessory Category’ for all accessories

3. The first ordertype, allows to first select a main product, and only then the accessories

4. Mark all product categories without ‘accessories –‘ in the name

5. The next order type allows to ONLY select accessories, as main products

6. To do this, mark all Product Categories that hold ‘accessories –‘ in the name, not the others
