Requesting dependent picklist functionality, i.e. if I have two picklists fields and select a value in the first picklist, then have built in functionality to only show related picklist values in the second field. An e.g would be:

1. Picklist one contains a list of all California counties.
2. Picklist two contains all cities in California.

If I select Contra Costa County in picklist one, then picklist two shoudl only shows cities in that are in that County.
