Bulk editing, creating, and deleting bundles
You can manage your bundles just like any other product in your Shopify store. The Shopify product list lets you filter and bulk edit products using built-in actions such as edit, add, and delete.
For more advanced editing, select the bundles you want to edit and click Bulk edit. Only certain bundle properties can be edited through the Shopify editor. To edit additional bundle properties, use the bulk import feature. For more details, refer to: How to bulk import bundles.
To edit a bundle on Simple Bundles from Shopify, go to the bundle product on Shopify, select More actions and click Edit bundle in Simple Bundles.
Bulk deleting items from fixed bundles using a CSV file
You can also bulk delete child items from parent bundles using a CSV using the import and export features.
