Drop-down dynamic select

Hello,

Details of the issue:
We have configured three forms as follows:

1. Form1 contains a single field for typing a “Country.”

2. Form2 includes two fields:
A “Country” dropdown field dynamically populated from Form1.
A “City” field where users can manually add cities.

3. Form3 includes three fields:
A “Country” dropdown field dynamically populated from Form2.
A “City” dropdown field dynamically populated from Form2.
A “State” field where users can manually type their state.

The issue:
Currently, the “City” dropdown lists all available cities, regardless of the country selected in the “Country” dropdown. This behavior makes it difficult for users to find cities relevant to their chosen country.

Request:
I would like to configure the “City” dropdown to display only the cities that belong to the selected country. Could you please advise on how to achieve this?
