Sorry, I didn't get it as I am completely new to this GSAP and I am not able to visualise the structure/approach you are sharing. It would be better If you can provide a quick demo for the same.
And one more thing, If I pinned the element, then the previous element will not have that scroll effect,I want that also be scrollable like below but with the various content. And that content should be accessible first before scrolling the next section. https://codepen.io/GreenSock/pen/QWjjYEw
