I'd like to sell meat in my magento store. Therefore I want a dropdown for weight from 500g to 12000g in 500g steps. I tried to implement this by using "custom options". The problem is, that the stock only decreases by 1 per order (works as designed ^^).
You should use Configurable product with weight attribute variation.
- Catalog -> Attributes -> Manage Attributes -> Add New Attribute "Meat Weight"
- The attribute should be drop-down, Use To Create Configurable Product & Global.
- Create all options under this attribute like 500g, 1000g, ..., 12000g
- Now Create a Configurable product with attribute "Meat Weight", enter the description and in Associated products, create simple products under this configurable product.
Please let me know, if you face any problem implementing the solution.
