How to Show Contacts in a dropdown based on selected Account on Custom page?

Hello Creatio Community,

    I want to display Contact List in a dropdown. The Contacts should be dynamically filtered based on the Account selected in another dropdown on the same page, As Shown in below Image.

Requirement:
    When the user selects a particular Account, the Contact dropdown should update to display only the Contacts associated with that Account. Both fields Account and Contact are linked to Custom object in Creatio.

Questions:
1. How can I dynamically filter the Contacts dropdown based on the selected Account?
2. Are there specific methods or best practices in Creatio Freedom UI for implementing such a dependency?

Thanks & Regards,

Ajay Kuthe.
