Collasping menus

[tickler]

Is there a script/plugin to do expanding/collapsing menus on blogs.

I want to be able to expand months==>days, categories==> sub-categories, etc. and still maintain the automatic linking.

eg.
2007 expands to
2007-Jan.
2007-Feb.
2007-Mar.

...or...

Teens expands to
Teen_SoloGirls
Teen_SoloGirls_RavenRiley
Teen_SoloGirls_RavenRiley_Nude
Teen_SoloGirls_RavenRiley_Anal
Teen_SoloGirls_TightTeela
Teen_SoloGirls_TightTeela_Facials
Teen_SoloGirls_TightTeela_Toys
Teen-BlowJobs
Teen-Anal

I also have uses for this in the non-adult world. Especially for a webmaster shopping site.
