Hi @PMwebdev ,
It is a complicated request and it is difficult for someone to guide you in detail. I recommend hiring a professional for it, they will help you edit everything quickly. Refer group: https://community.shopify.com/c/Shopify-Ecommerce-Jobs/bd-p/shopify-job-board
Or you have experience in coding, you can clone the code from collapsible-content.liquid file and customize it, it will work fine.
