Yes, WC Quick View supports variable and grouped products.
For Variable Products:
Customers can select variations (e.g., size, color) directly within the popup before adding the item to the cart.
For Grouped Products:
The popup will display the grouped items list, allowing users to choose quantities for each item.
Note:
Ensure your theme or any optimization plugin doesn’t interfere with variation scripts.
If variation dropdowns do not load, check for JS conflicts or caching issues.
