I was hoping to avoid extending/re-implementing the base effects, as
I'd like to build a Cookbook of scriptaculous code which use the core
effects.
After playing with it some more, I found a way around it.
- Keep some JS globals for whether the dropdown is open, changing,
or eligible to be closed.
- On mouseover, fire the effect, tweak the globals, and plant a
timeout for closing the dropdown.
- The timeout loops unless the vars are set for closure, at which
point is fires the reverse effect.
Might have been nice to do with callbacks/partial effects, but this
seems pretty robust. Thanks all.
