Capturing and Displaying Day of Week Selection in Storyline 3

Hello everyone! I'm currently working on an interaction in Storyline 3, and I'm seeking help with capturing and displaying Day of the Week selections.

On the 1st slide, I have a drop-down menu containing the days of the week in order: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday. Users can choose one or more days from this drop-down.

On the 2nd slide, I want to display the selected days horizontally next to each other in the order they were chosen. For instance, if a user selects "Monday" and "Wednesday" from the drop-down, both days should appear side by side on the 2nd slide.

I believe that using JavaScript might be the best approach to achieve this functionality, but I'm unsure about the specific implementation. Any guidance, suggestions, or code examples would be greatly appreciated! Thank you in advance for your help.
