Select your range of rows
Data|Group and outline|Group

repeat as required.

If you put the task in each line (say column A), you could use data|Subtotals to
create these outlining symbols--and if you had hours (say) in a column, you
could even sum that column.

I would like to type in a task title (in excel) and then create a sublist of
what needs to be done to complete the task. Ideally the sublist would be
hidden until opened, similar to the expand/collapse folders in Outlook. Is
there anything like that available?
