expandable / collapse side menu

[ricksonlo]

I am looking for a extnesion which is just like the joomla default menu module with the ability to expand / collapse vertically.

I have searched and almost tried all the non-commerial menu modules supported Joomla3. Almost all are accordion menu - means the submenus are slided from the side of its parent and are on top of their parent.

What I am looking for is a older fashion one like...

Menu 1
Menu 2
Menu 3

When I click on Menu 2, a simple expand animation occurs and it becomes

Menu 1
Menu 2
- Menu 2 Sub 1
- Menu 2 Sub 2
Menu 3

When I click on Menu 2 again, the menu collapses and back to original state. The main point is .. Menu 3 will also move down as Menu 2 expands, which I couldn't find similar one in the available extensions ..

I am glad if someone can point me to an extension like this (or even can be doable by default setting?)
