Checklist is a very useful attribute that can help you categorize your items even further. For example, you can use the Checklist to create subtasks within one task, and then mark them as done once they are completed.
Creating this attribute works a little differently. Once you give your checklist a name (e.g. ‘Subtasks’), it will appear on the item sidebar/modal.
From there, you will be able to add as many subtasks as you want into your checklist by clicking on the field that says 'Add' and writing down your tasks.
These subtasks will only be a part of the item where you create them, but you will be able to create different checklists in other items.
