checklist items for a task

checklist items for a task

Is there a way to have a check list for a task?
For example:

Task List 1
      Task A
            check list item 1 
            check list item 2 
            check list item 3 
            check list item 4
      Task B
            check list item 1 
            check list item 2
            check list item 3


checking off 2 /4 items in Task A would result in Task A being marked 50% complete

Is this possible?
