           <div class="short_description">{{description}}</div>
           <div class="price">
                <span class="list-price">&euro;{{list-price}}</span>
                <span class="sell-price">&euro;{{sell-price}}</span>

    </template>
</amp-list>

<amp-state id="myState" src="/dropshipping/__AMP_get_products.php"></amp-state>
    <form method="GET" action="/dropshipping/__AMP_get_products.php" action-xhr="/dropshipping/__AMP_get_products.php" target="_top"
        on="submit-success: AMP.setState({
            myState: { items: myState.items.concat(event.response.items)},
            product: {index: product.index + 1,
            hasMorePages: event.response.hasMorePages}
        });">
        <input type="hidden" name="index" value="0" [value]="product.index">
        <input type="submit" value="Mostra altri prodotti" [class]="(product.hasMorePages == false ? 'hide' : 'ampstart-btn caps m1 mb3 show')">
    </form>

Try AMP-Live-List . AMP-List is static.
