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!
