can fields be made conditional?

is there a way to make a cb field conditional based on a check box, for example if we have a check box for Are you a Manager? and a field right below for Department.
the Department field will be disable if the Are you a Manager check box is left un checked if it is checked the field is enabled and required?

Thanks

I'm just digging into the whole question of conditional display myself so this could be a case of the blind leading the blind; but krileon's tutorials have helped me. Try this link: www.allmysocials.com/tutorials and good luck.

New CB Conditionals plugin - just released in incubator www.joomlapolis.com/cb-solutions/incubator - looks very promising.
