Hello,
You can find the instruction on how to configure the attributes in the product list here: https://xtemos.com/docs/woodmart/variable-products-swatches/
You can show only one attribute in the grid and there is no option to show the quantity selected. As soon as the product has been added to the cart one can change the quantity in the shopping cart.
Woocommerce search finds the product on keyword only. Our theme has expanded the function now you can find product by SKU.
Best Regards
