Customizing Menu Completion Checkmarks in Storyline 360 Modern Player

Hi Everyone,

I'm working on a course in Articulate Storyline 360 using the Modern Player, and I've noticed that the built-in menu completion behavior marks a menu item with a checkmark as soon as the learner visits the corresponding slide.

My requirement is slightly different.

Instead of displaying the checkmark when a slide is merely visited, I'd like the menu item to be marked as complete only after the learner has fully completed the slide, such as:

• Viewing all content on the slide
• Completing all required interactions
• Visiting all layers or tabs
• Finishing an activity or knowledge check
• Reaching the end of the slide timeline

Currently, the menu checkmark appears immediately upon entering the slide, which does not accurately reflect the learner's completion status.

My questions are:

1. Is there any way to customize the built-in menu completion tracking in the Modern Player?
2. Can the menu checkmark be tied to a custom completion condition rather than slide visitation?
3. Has anyone found a workaround or best practice to display completion status only after all required interactions on a slide are completed?
4. Would creating a custom menu be the only option, or is there a setting, trigger, variable-based approach, or JavaScript solution that can modify the behavior of the built-in menu?

I would appreciate any guidance, recommendations, or examples from those who have encountered a similar requirement.

Thank you in advance for your help!
