In the oxygen demo the black menu on the left sidebar shows the categories. The BOOK category has a child category, ARTWORK
which can be navigated to as an horizontal sliding drawer from BOOK.
I have been unable to get this effect by adding the categories using the Menus (even though my categories are already organized with parent/children structure).
How do I get this effect?
Thank you for your help.
The blog I need help with is jagworks.wordpress.com.
