[Vaibhavi_Gabani]

i'm trying to call limited number of product-grid-items and manually selected products as well. but while calling it take too much load and it page response corrupts. how can i solve?

{% for block in section.blocks %}

{%
render 'product-grid-item',
block: block,
product: block.settings.product,
product_image: block.settings.image,
product_image_alt: product_image_alt,
%}
{% endfor %}
