Hi Sir , I am a noob in iOS development so can you tell me how to make it horizontal flow instead of vertical and can I support iOS 7 also with this ?

I have around 100 items in the collectionview with picture and text. When calling self.toggleExpansionForSectionAtIndex(recognizer.section, animated: true, withDuration: 0.5);, if there are 10,20 items in the expanded section it's fine. When it contains 100 it takes around 1.5 seconds which is laggy for the user. Any solutions? (Maybe because each time i expand, the whole collectionview loads?) Thank you!

set features to set and customize background color or image and insets and corner radius for every section

The collection view drawers are cool. Its really pretty and powerful they grow and shrink. In each expanded drawer can i set direction of collection view as horizontal or vertical?
