Insert content into sections

Hello everybody.

After a very long search we finalle discovered Basepress and completely fell in love with it because it does exactly what we need.

But I have one question:
Can we insert content into the sections? So when you click on the top section (not an article) there will be something shown?

I hope somebody can understand what I mean.

If you need additional information please ask me.
Thanks in advance.
