Generate a large dynamic javascript checkbox list menu thingy

[eluser]johnwbaxter[/eluser]
I need to generate a javascript checkbox list with parent and children structure that can be expanded and contracted and also supports intelligent checking where if you tick the parent it ticks all the children.

Errr, has anyone come across something like this? Open source preferable!

If anyone can lend any help i would be eternally grateful!

You mean something like this or this but then with added checkbox support.

[eluser]johnwbaxter[/eluser]
Yes but without the table stuff!

Also it would be nice to be able to load the children on the fly to save loading a huge list at the start.

This is nearly exactly what i want.
