Product grid excerpt

Hi,
Afaik this is not possible. WooCommerce replaces the “excerpt” field with the “Product short description”. However you could simply use the main description box as excerpt box. Then add this code to the functions.php:

function woocommerce_after_shop_loop_item_title_short_description() {
	global $product;
	if ( ! $product->get_description() ) return;
	?>
<div itemprop="description">
		<?php echo $product->get_description() ?></div>
<?php
}
add_action('woocommerce_after_shop_loop_item_title', 'woocommerce_after_shop_loop_item_title_short_description', 5);

to display the main description below the product title on shop pages.

If you don’t want to display the description tab on the product single page you can also include this code in functions.php:

// add this to functions.php, a custom plugin, or a snippets plugin to remove the description tab in woocommerce
add_filter( 'woocommerce_product_tabs', 'sd_remove_product_tabs', 98 );
function sd_remove_product_tabs( $tabs ) {
    unset( $tabs['description'] );
    return $tabs;
}

Best regards,
