Referring to the picture above, I don't know the best way to do this for performance, but I'm guessing I'd go about it like this…
Obtain a section header cell from IGGridViewSectionHeaderCell +gridView:cellForSectionHeader:
Create and size three UIViews (light purple boxes) and place them in the section header cell.
UIView 1 has the circular icon which would either be an image, or be drawn in code.
UIView 2 would be a label
UIView 3 would be an image.
Each of the UIViews would need a tap gesture recognizer
The UIViews 1 and 2 would have a tap recognizer that would toggle the expand / collapse behavior
UIView 3 would have a tap recognizer that would take you to another gridview.
Hey Dave
Id derive from the section header cell and extend it that way.
I'm taking a long weekend, but when I come back I could throw a sample together for you. Not sure how soon you need this.

I'll try and tackle it, but I always love a good sample.
Throw one up when you get back if it's no problem
Have a good weekend.
Dave.
