Interactive word Bank question

Hi Everyone.

I am brainstorming how I can design a slide with a word bank of 15 words in Storyline 360. Users would choose 5 of 15 words which describe them best and then on the next slide or layer, they would only see the words they have chosen, preferably in different colors.

I feel like I am having a mental block with how to properly use "choose many." I have seen the example that exists where a user would choose soccer teams who they expect to win, basically whittling down from a list/bank of teams down to a final four, so I can see it can be done, but I am not able to see the "guts" of that course.

Any suggestions would be greatly appreciated.

Thanks,

Peter
