The priority value specified on tabs allow youto set an order to show them in product detail page.
When you assign a priority value to the tab, consider the values already used from WooCommerce tabs.
- 10: tab “Description”
- 20: tab “Additional information”
- 30: tab “Reviews
For example, if you wanted your new tab to be shown among “Description” and “Additional Information” WooCommerce tabs, you should insert a priority value ranging from 10 to 20.
