Dynamic checklists from array

I am building a course that requires the learner to choose from a list of supplies at the beginning of the experience.  Throughout the course, they will then use these supplies.  There are 8 overall categories of supplies that they might use, with 10 options in each category.  While I can create each item in each list as its own variable, I'm wondering if there's a way to build the lists from arrays and have the items that have been chosen appear dynamically.  This would be fairly straightforward to do in HTML + Javascript.  Do I have to create each item as its own variable or if there's a way to build and track list items dynamically?
