Populating a page using learner's selections (variables)

Hi everyone

I tried searching for this but couldn't find anything--it's hard to describe it so my apologies if it's addressed somewhere already.

I've attached a screen grab of a slide where the user would select some actions they want to work on. I'd like to then populate the next page with the selections they made on the previous page--turning it into an action list for them. I realize I can do this easily with variables and triggers.

But how would I format the Action List page when I'm not sure which items they are going to choose? for example. How do I avoid blank lines and weird formatting and make it into a properly formatted list?
