In some Shopify themes, the seating map link may appear more than once after changing variants or updating the product form.

This happens because some themes dynamically re-render the product form when variants change, which can cause the seating map container to be added multiple times.

The solution below keeps only one seating map link visible and automatically cleans up duplicates.

Step 1: Open the Theme Editor

In Shopify Admin:

Online Store → Themes → Customize

Open the product template where your event product is displayed.

Step 2: Add a Custom Liquid Block

In the product section:

Click Add block
Select Custom Liquid
Place the block where you want the seating map link to appear

Step 3: Paste This Code

Paste the following code into the Custom Liquid block:

<div data-evey-seat-option></div>

<script>
document.addEventListener("DOMContentLoaded", () => {

  const mount = document.querySelector('[data-evey-seat-option]');

  if (!mount) return;

  const moveSeatMap = () => {

    const links = document.querySelectorAll('.evey-seating-url-container');

    if (!links.length) return;

    // keep only newest generated link
    const latest = links[links.length - 1];

    // avoid duplicate move
    if (!mount.contains(latest)) {
      mount.innerHTML = '';
      mount.appendChild(latest);
    }

    // remove remaining duplicates
    links.forEach((el) => {
      if (el !== latest && el.parentNode) {
        el.remove();
      }
    });
  };

  // initial cleanup
  moveSeatMap();

  // monitor variant changes / re-renders
  const observer = new MutationObserver(() => {
    moveSeatMap();
  });

  observer.observe(document.body, {
    childList: true,
    subtree: true
  });

});
</script>

What This Does

This script:

Keeps only one seating map link visible
Automatically removes duplicates
Repositions the seating map link into the Custom Liquid block
Continues working after variant changes or dynamic theme updates

Recommended Placement

For best results, place the Custom Liquid block:

Near the seat selector
Above the Add to Cart button
Inside the main product form area

Important Notes

This is a theme-level workaround for themes that dynamically re-render the product form
The seating map link itself is still generated by Evey
No changes are made to your event or seating configuration
