Hi all, i'm new to concrete5 and css.
I've started a website (my 2nd one with C5) and i have to build a menu using Autonav.
This one have to look like this :
(see attached file)

Actually i have done the style (arrows, text, changing arrow when a part is clicked)

But how to display childs only when the dropdown menu is pressed ?

I know how to edit the autonav visual style but not this hard (for me) peace of work :s

Please help (and sorry for my poor english, if someone speak french ...)
