[Vertical Alphabetical Scroll] [Vertical Alphabetical Scroll] container selector and scroll not working
Question
vertical-alphabetical-scroll
Mobile icon
Forge asset by Henrique Batista

I am trying to use the forge component Vertical Alphabetical Scroll on a mobile app to scroll through a list of people, I've created the container for the list which is in the scrollable area of the screen and made a custom class for it and referenced that class to the forge component in the scrollableContentSelector input parameter. I also made the letter headings in the list and gave them the data-letter attribute of the letter in the heading but it still will not scroll. 

I can't seem to find any instructions for this forge asset so it is making it very difficult to troubleshoot.

Hi Jacob,

Based on the demo of that Forge component, your VerticalAlphabeticalScroll block is positioned above the list. Try placing it below the list instead.
I also recommend downloading the demo OML to check the correct setup and replicate that approach.

Thank you Mihai,

The demo OML helped a lot. It turns out you use ".active-screen.screen-container" as the input for the scrollableContentSelector instead of matching a class to the container and that got the scoll to work properly.
