For those who have the same problem as @thiagoRcosta and I, you can add that bit of JS somewhere on your site:

document.addEventListener("DOMContentLoaded", function() {

    let quantityInputs = document.querySelectorAll('input[name="quantity"]');
    quantityInputs.forEach(function(quantityInput) {
        quantityInput.value = '1';
    });

    let variationChoices = document.querySelectorAll('.value select');
    variationChoices.forEach(function(variationChoice) {
        variationChoice.value = '';
    });

});

It definitely isn't the most elegant solution, but at least it hides the problem until someone smarter than me can fix it 😬

How I can display product variations dropdown select on the Cart page?

Hi, this code works exactly how I want. Many thanks! I have only one problem (using Jupiter X theme with Elementor editor and JetWooBuilder): For single products it shows 2 add to cart buttons. How can I remove this? I don't want to add single products with variations to fix this bug. It seems the first add to cart button ignores the stock status, the second doesn't ignore it but redirects to product page which I don't want to show. It has to show and work like the product above. So the second button works correct but I want to show the price and stock status like for variable products and don't want to redirect to product page if not enough products are on stock. Many thanks.

Single product:

Added code:

$attribute_keys = array_keys( $product->get_attributes() );
?>

<form class="variations_form cart" method="post" enctype='multipart/form-data' data-product_id="<?php echo absint( $product->id ); ?>" data-product_variations="<?php echo htmlspecialchars( json_encode( $product->get_available_variations() ) ) ?>">

	<?php endif; ?>

	<?php do_action( 'woocommerce_after_variations_form' ); ?>

<?php } else {
	
echo sprintf( '<a rel="nofollow" href="%s" data-quantity="%s" data-product_id="%s" data-product_sku="%s" class="%s">%s</a>',
		esc_url( $product->add_to_cart_url() ),

		esc_attr( $product->get_sku() ),
		esc_attr( isset( $class ) ? $class : 'button' ),
		esc_html( $product->add_to_cart_text() )
	);
}

}

can this be added as shortcode?
