the requirement is this: you want to implement a page similar to ele.me.
for example, the label on the left side of a store has "best-selling list", "drink" and "snack". Wait a minute. On the right is all the merchandise of the store. The desired effect is that when you slide the list of items on the right, when you slide to a label bar, the label corresponding to the left sidebar is highlighted. Of course, you can also directly slide the sidebar on the left, click to select the desired label, and smoothly scroll to the item on that label.
could you tell me how to implement this requirement, or are there any off-the-shelf components to learn from?
