Hi Adam,

Thanks for contacting us here.

Unfortunately, we don't have any recommended plugin in this are to introduce to you. You can kindly test the common ones on your site. 

Fortunately, we offer free customization service in which we can help you solve the incompatibility issues with third-party plugins, so you can choose a preferred sticky add to cart plugin for your site and we will help you fix any possible issues.

Best regards.

Hi Adam,

In this case, it is best if you can discuss with our developers directly. I have transferred your ticket to one of our developers to help you with that. 

He’ll be looking into your question and responding with specific instructions as soon as possible. 

Please stay patient as we're having very heavy workloads, it might take some time for our developers to reach back.

Best regards.

About "Sticky add to cart", we'll release this plugin at the end of 2021. Hope you can wait for it.

function woosb_sticky_alert() {
    ?>
    <style>
        .woosb-alert-sticky {
            opacity: 0;
            visibility: hidden;
            display: none;
            width: 100%;
            text-align: center;
        }
        .sticky-add-to-cart--active .woosb-alert-sticky {
            opacity: 1;
            visibility: visible;
            display: block;
        }
    </style>
    <script type="text/javascript">
      jQuery(document).on('woosb_check_ready', function(e, is_ready, is_selection, is_empty, is_min, is_max) {
        if (!is_ready) {
          var alert = jQuery('.woosb-alert:not(.woosb-alert-sticky)').text();
          if (jQuery('.woosb-alert-sticky').length) {
            jQuery('.woosb-alert-sticky').html(alert);
          } else {
            jQuery('.sticky-add-to-cart').prepend('<div class="woosb-alert-sticky">' + alert + '</div>');
          }
        } else {
          jQuery('.woosb-alert-sticky').remove();
        }
      });
