Hi,

Shop section is planned for redesign mainly because of the variable products.

Currently I can provide you with alternative to open the product page instead of add to cart button.

Insert the following code in your theme / child-theme functions.php file:

/**
 * STEC MOD:
 * 
 * Variable products "Add to Cart" button is replaced by "View Product" 
 * on click redirects to product page
 */
add_action('wp_head', function() {
    global $post;
    if (!is_a($post, 'WP_Post') || (!has_shortcode($post->post_content, 'stachethemes_ec') && 'stec_event' !== $post->post_type)) {
        return;
    }
    ?>
    <style>
        .stec-view-product-btn {
            white-space: nowrap;
        }
        
        
        .stec-layout-single-media-small .stec-view-product-btn,
        .stec-media-small .stec-view-product-btn {
            margin-top: 20px;
        }
    </style>
    <?php
});
add_action('wp_footer', function() {
    global $post;
    if (!is_a($post, 'WP_Post') || (!has_shortcode($post->post_content, 'stachethemes_ec') && 'stec_event' !== $post->post_type)) {
        return;
    }
    ?>
    <script type="text/javascript">
        (function ($) {
            // In calendar page
            $(document).on('onEventToggleOpen', function (e, data) {
                var product = data.$instance.find('.stec-layout-event-inner-shop-products .stec-layout-event-inner-shop-product');
