possible Bundle C = bundle A + bundle B

Hi @futureyoon,

For your information, special product types such as Smart Bundle/ Smart Grouped/ Smart Composite cannot be added to as part of any other product types. These special product types are equal and work individually. These special product types only support simple product (marked “simple #…”), variable products (marked “variable #…”), variations (marked “variation #…”), and subscription products (marked “subscription #…”). as their sub-products inside.

In case you would like to add extra products to a Smart Bundle/Grouped/Composite, please use the WPC Frequently Bought Together or WPC Force Sells plugin to add other parts as extra options for the composite product. You can use the WPC Frequently Bought Together plugin to add optional extra products to a smart bundle/ grouped product/ composite product: https://doc.wpclever.net/woobt/bought-together-setup/

Or use the WPC Force Sells plugin to add required extra products to a smart bundle/ grouped product/ composite product: https://doc.wpclever.net/woofs/force-sells-setup/

These extra items will be displayed under the main bundled products/ grouped products/ component products on that product page.

NOTE: Both Bought Together and Force Sells items can be added to the same main product so that you can have both optional and required options in a single offer.

For more information, you can kindly refer to the online documentation of our plugins on this site: https://doc.wpclever.net/. We also have a blog about how to combine plugins, you can obtain some more information here: https://wpclever.net/5-best-woocommerce-product-bundling-tools-for-skyrocketing-your-sales.

Best regards.
