Creating a Style Sheet that works like Windows Explorer

Hello,

I wanted to know if someone can guide me in the right direction. I am in the process of creating a style sheet that retrieves information from another source. Basically, a developer created an xml application that creates a hierarchy of files. I am looking for information on how to display this information.

How would I create a style sheet that works like windows explorer? Files would be displayed in a hierarchy. The left hand view would be see files. Once one is clicked the children of the parent would expand. The right hand view would display files.

File 1
---Child 1
---Child 2
---Child3
File2
---Child1
---Child2
---Child3

3 Steps.
1. Find the javascript to create a Treeview

2. Find the javascript to create a master-slave like display.
This isn't exactly it, but the principle is the same.

Just change the update a combobox to updating the contents of your secondary div on the right hand side.

3. Convert your source into (2) using stylesheet.

This is great...Thanks for the guide. This is plenty for me to work off of.
