Accordeon Menu V3 shows complete menu instead of just the part of it

Dear Cedric,
I have installed the new Accordean Menu today and followed al your instructions. Seems t work but there is one big issue. In de V2 it was possible to show all items under a main menu item. So, suppose you have a menu A, B and C and as sub menus A1,A2 B1, B2, and B3 and C1,C2,C3, C4, I had he option in the V2 to show in the accordeon menu A1, A2, A3 when clicking on A.
I have tried to re-get this behaviour but whatever I did, it didn't work. What do I wrong?

An example of the (good) old way can be seen her: website_A
and an example of the V3 (with the full menu (i.e. A1,A2,B1,B2,B3,C1,C2,C3,C4) ) can be found here: Website_B

Already thanks,

Arjan

Hi

I shall release a new version to fix it in the coming days
