[Buy button] how to display all products on a same page?

Hello,

Need advice urgently.

I have created a page with buy button feature. A simple page where customer knows the products well, no need explanation, just to give a quick order process.. The problem is that I have more than 100 products, and the page only shows 20 products and the customer needs to click “next page” many times to see the whole range of products.

Any way to show the entire products in one page? The script is as following,

the sample page is ("https://jin-global.com/pages/ks-link-order")

Please help! Your help is very much appreciated. Thank you.
