Re: Navigating JSON sub-arrays dynamically

[Pete Helgren <pete@xxxxxxxxxx>]

Couldn't you use something like  selectCombo for jQuery v 1.2.3 
(combo.js) plus populate.js. Combo.js handles the combo and when you 
make a selection populate fills in the fields on your page.

Or maybe there is something unique in your implementation that I am missing.
