New Post: Hierarchy of work items

Is there a way to set up a template so that work items are shown hierarchically?

i.e.

1.0 My Epic Requirement

  1.1 My sub-requirement
  1.2 Another sub-requirement
          1.2.1 A sub-sub requirement

etc.

when I create a template that has

1.0 title

  description
  1.1 title
        description

then I get the same work item repeated for 1.0 and 1.1, otherwise if I create a template with just

1.0 title

  description

then the template ignores the hierarchy and I just get requirements shown as 1,2,3,4 etc.

how to I create a template that will respect the child work items?
