# Checkbox
A checkbox element lets learners select one or more options from a list. It’s useful for self-assessment or task completion. You can also use it to control navigation by requiring a learner to confirm a step (like, "I have downloaded and reviewed the document") before moving on.
#### Double-click on an element to view its settings.
