This plugin will hide the WooCommerce “Update Cart” button and reload the quantity changes dynamic over jQuery. You don’t need this extra click anymore!
This Plugin is based on a posting on StackExchange related to WordPress developers. I modified the basic concept and created a plugin out of it that WordPress users with less experience in PHP can integrate this function easily without destroying their functions.php file.
There are no options. Just activate the plugin and it will works.

Important: This plugin is a free add-on for the official <a href="https://woocommerce.com/products/product-bundles/" rel="nofollow ugc">WooCommerce Product Bundles</a> extension. It was created to validate and refine a feature that is now included with Product Bundles.
<h3>Documentation</h3>
Up until version 6.4.0, <a href="https://woocommerce.com/products/product-bundles/" rel="nofollow ugc">WooCommerce Product Bundles</a> did not include any options for selling fixed- or variable-size bundles, such as cases of wine, six-packs of soap, or candy boxes.
This feature plugin added two new options under Product Data > Bundled Products:
<ul>
<li>Items required (≥); and</li>
<li>Items allowed (≤).</li>
</ul>
Prior to version 6.4.0, these were used to set a minimum or maximum quantity of bundled items that customers should choose to make a purchase.
