I wanted to use the Pure Drawer menu in one of the qvws I was working on but didn't know how. Good thing I ran into the dropdown menu extension (http://community.qlik.com/docs/DOC-5997#start=50) by Petra Bloem . I used her scripts as the base for my menu extension. I left the functionality for submenu items as I have plans to use it for another menu extension in the near future. I have set the menu over on the left side with slide in on top as the effect.
Anyway, feel free to provide feedback in case you see any issues or have suggestions.
