    This code hides the 'rent' parameter depending on whether the 'city' parameter is checked.

    def constrain(model, var, val):
	if var=='city':
		if val: model.params.hide('rent')
		else: model.params.show('rent')
heli.params.add('city', 'City', 'check', True, runtime=False, callback=constrain)
