# Fera Product Reviews App

Keep Fera review badges showing correctly on product cards inside the filtered product grid.

## What this does

Fera normally draws its star-rating badge onto a product card once, when the page first loads. Because Smart Product Filter & Search re-renders product cards every time a shopper filters, sorts, or paginates, that badge needs to be redrawn on each refresh — otherwise ratings disappear as soon as a shopper interacts with the grid. Fera also needs one small snippet added to your theme.

## Turn on the integration

1. In the app, go to **Settings > Integration**.
2. Search for **Fera** and turn on **Enable integration**.
3. Click **Sync now** on the Home dashboard.

## Add the theme snippet

1. Go to **Online Store > Themes > Edit code**.
2. In `theme.liquid`, add this near the end of the file:

```html
<script>
window.addEventListener('globoFilterRenderCompleted', function () {
  setTimeout(function () { fera.forceRefreshContent(); }, 1000);
});
</script>
```

3. Save.
