Hi

I can't find the documentation. Can I overrule shipoment methods?

More specifically, if customers in our shop buy dog food (heavy) shipment shipment has to be GLS business service.
We sell several other items (not heavy), and normally people can choose to have them delivered to parcel shop or by the postal service.

So how do I remove the other options when people choose the buy both dog food and other items. Since dog food can only be delivered using one shipment method this method has to aply to all other items in this case.

Does my problem make sense?

One shipment method cannot disable another method.
However, if you use my shipping by rules plugin for the postal service method (which should not be offered when dog food is included in the order), then you can simply check for dog food in the rules and use NoShipping in that case. This will result in only the GLS method to be offered when dog food is included in the order.

The GLS method, though, will always be offered, since the GLS shipping plugin does not have any way to limit its application based on the items in the cart.

The postal service rules would be (assuming dog food can be identified as all products in category 13):
Best regards,
