Description: If your enquiry for variable products (with attributes) is working correctly in both the enquiry cart and email, you don’t need to change this setting.
Simple Explanation: This setting is used when you’re adding a variable product to the enquiry cart, but its attributes (like size or color) aren’t being included in the cart or in the enquiry email. To fix this, you need to add a JS selector in this setting.

When a variation is selected, a variation ID is added to an HTML element with the class variation_id. PEP (Product Enquiry Pro) pulls this variation ID to include in the enquiry cart.
However, if the structure of the product page changes, PEP might not find the variation ID. As a result, the product’s attributes won’t appear in the enquiry cart or email.
If this happens, you need to add a JavaScript selector in PEP’s settings under [Product Enquiry Pro > Settings > General > Selector for Variation Id] so it can correctly fetch the variation ID. You can try adding .variation_id:first-child as a solution, as shown in the example screenshot.
