Use a spry detail region as a master region for another data set

Hi.
How can i do this.
Load  in a spry region my main news categories.
When I click on them  another div loads the titles that correspond to the current category I ve clicked.
Then click in one of those  titles and in another div load the full text.

I want to this with the spry framework.
I tried to do this with master detail region. I manage to get the main categories and Titles of those categories to work. My problem is that I cant load full text of those titles in the third div.

Thank you.
