Pop-out menu which tracks progress on page

Question

Hi, I'm trying to create a pop-out menu like the one here - when i inspect it, it appears to be a "progress-indicator__list-item".
 

Crucially I want my menu to highlight the respective heading when that page loads (the example here turns gray). I've set my example up as an MSO which is switched on and off using a button. But I can't find a way to trigger specific states for the respective page load.

Any ideas on how to approach this?
Thanks!

You should be able to select "Go to State" in the buttons panel to trigger a specific state (that you set up with the Object States panel). I'd be happy to take a look at your file. Can you send your InDesign package and html output files to https://ajarproductions.com/pages/contact.php?category=in5
