Hello @LeftyX, thanks for your reply..
I see the link, and i found one which is on the way, but needs some tweaking to solve my problem ..
http://play.ionic.io/app/40f60f097fb2
Him have the subcategories, but when i open, the grandchildren (third level), can not be clicked individually.. When click in anyone, make the accordion close, and i need put a link in anyone.
Other problem is the question about the icon.. I need to open accordion only if clicked on icon, because in the 'name' of accordion, will have a link.
Thanks.
