Hi Davinder & Natalia,

Thank you for contacting WPClever Support Forum.

For your information: 

• In the free version of our plugin, only simple and subscription products can be searched and added. 
• Instead, free users can now add unlimited products as they prefer. 
• Variable products and variations are only available in the Premium version.

In case you need further instructions, kindly refer to this online documentation: https://doc.wpclever.net/.

Best regards.

Hi Davinder,

In that case, you can use the WPC Frequently Bought Together or WPC Force Sells plugin to add additional products to the main smart bundle. 

You can use the WPC Frequently Bought Together plugin to add optional extra products to a smart bundle/ grouped product/ composite product. 

Or use the WPC Force Sells plugin to add required extra products to a smart bundle/ grouped product/ composite product. 

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.

In case you don't want to purchase other Premium plugins, you can keep the additional item as simple products. The free version of both these plugins only support simple and subscription product. If you would like to use the variable product or selected variations, it's required to purchase the Premium.

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.
