Popup contact form - by Darja - on WordPress WooCommerce support

Hello,

You can use a hook in function.php of child-theme to add the button https://businessbloomer.com/woocommerce-visual-hook-guide-single-product-page/
For example, add a button that calls this “Popup content” http://prntscr.com/n3j5pq
http://prntscr.com/n3j8ze

add_action( 'woocommerce_share', 'contact_us_custom_action', 5 );
 
function contact_us_custom_action() {
    echo '<div class="custom-contact-popup"><a href="#etheme-popup-holder" class="etheme-popup">Contact us</a></div>';
}

custom CSS code –

.custom-contact-popup {
    margin-bottom: 8px;
}
.custom-contact-popup a {
    background-color:  green;
    padding: 5px 10px;
    color:  white;
}

Or you can try to use an additional plugin (we do not provide support for 3rd party plugins).

You are welcome!
