If you meant scrolling for content that overflows, you’ll need a wrapper container with fixed height. For this container, make sure it “clips” the content and is vertically scrollable.
Can you help me with, how can we hold the scroll in between. I did the same way but what's happening If will scroll only when we drag it but what I want to wait somewhere in between. In between if we leave the scroll bar then either it will shift to top or bottom position. Can we help me in making it possible that scroll bar will stay in between.
