Eremas

New to caspio bridge and DataPages so I was wondering if there was a way to filter records out of a field based on user input into another field. For example if a user were to select a district/state 'X' where they reside in, instead of listing all the towns that are found in the country in the next field, I want the field (dropdown) to list only the towns located in district/state 'X'. Any help would be much appreciated.
