Some common use cases:

    Dynamically highlight a nav element in the nav bar (check the demo for an example).
    Dynamically change selected element in a dropdown on scroll
    Dynamically highlight an item in TOC (Table of Content) on scroll
    Calculate the scrolling percentage progress
    ...and more
Scrollspy

đŸ”Ĩ Features

    Can be used to implement the scrollspy feature in Bubble or animate elements
    It works with any Bubble element (returns an element ID)
    It works for Repeating Groups as well (returns visible item / index)
    Works for both, Vertical and Horizontal Repeating Groups
    Get "Current Item", "Current ID", "Current Index" visible on the screen
    Plugin fires an event "Item changed" that you can use in your Workflows
    Setup rules, in which part of the screen an element considered as "visible"
Plugin supports 3 modes:
    1.
    Add Groups, Texts or any other element type on the page and define a unique ID for each element. When you scroll, plugin will provide you current element's ID visible on the screen.
    2.
    RepeatingGroup (Vertical). Add a RepeatingGroup element on the page. When you scroll, plugin will provide you current element visible on the screen and its index.
    3.
    RepeatingGroup (Horizontal). Same as 2 but for a horizontal RepeatingGroup.
