I'm trying to create a custom field on my transaction forms which contains a list which is dependant on another record. Say for example that I have a form that I can link to another to bring in a US State or UK County. From that field I then want to have a list driven from that giving a list of towns/cities within that state/county. Can someone give me some pointers in how I should set this up... thanks

Hi there, As I understand you're trying to show a list values based on selected value from another field. You need to use sourcing&filtering on custom fields to determine which list the data will taken from

Dependent Dropdown Lists is an application of Sourcing and Filtering

Thanks. You say I would use sourcing to "determine which list the data will taken from"... does that mean I would have multiple lists, eg a list for each state/county and that list holds all the records I want returned for that selection?

Yeap, Once I made one for custom address form which shows every counties from selected cities because system doesn't have city and county Information for Turkey

Hi Sorry, it's taken a while for me to be able to focus on this. I've been trying Friday and all day so far today to get this to work. I think I can manage to get this to work if I have the fields in the body of the transaction, but I want to have a list that is in the lines section based on a body field. Is this possible?
