this question comes up periodically here. look in the archive for a thread
called "Autocomplete plugin for multiple form fields from a JSON source".
the kernel is to set minChars to 0 and then when you send two 'click' events
to the field when you want the suggestions to pop open, e.g. inside your
.result() event handler for state input, put:
$("#city").setOptions({minChars: 0}).trigger('click').trigger('click');
or it could go in an onfocus handler on the city field, as you wish.
