[jQuery] What would be the best way to do this / does this plug in excist


Hi
I Need to make the following.
link1
link2
link3 +
link4 +
link5 +
if I click the + image after link3 i have the following
link1
link2
link3 -
link3a
link3b
link3c
link4 +
link5 +
and if i click the - image it will collapse again
Preferably with an unordered List.
Before I start reinventing the wheel, does this already exist somewhere?
