I'm converting a real estate review website from standard HTML to using Movable Type as the CMS and so far it's working like a charm. I'm having one problem. The top level categories are the type of property - land development lots, presales, etc - and the subcategories are the location of the property. I want the front page to list only one category and to show the entry titles of these entries within their subcategories like this:

Presales (parent category)
--location (sub category)
----entry title
----entry title
----entry title
--other location (sub category)
----entry title
----entry title
----entry title
--other location (sub category)
----entry title
----entry title
----entry title

Any thoughts on how best to do this?
