J-BusinessDirectory - Custom Attribute functionality help

I'm hoping for some help with a custom field attribute, or modifying how this custom attribute works. Here's what I'm trying to accomplish.

I would like to create a custom attribute select list which changes by a select list. So, for example:

I would like to list States: 1, 2, 3

and based on that click, select County: 1, 2, 3

so i dont need to list all possible counties.

Is something like this possible? IE parent with child select lists...

Thanks!

Hi,

Currently the custom attributes are not linked to each other and the connection is not possible.
