Change the data of select widget based on value selected in another select widget on the same form (country - city)

Hi everyone,

I need to change the values in select widget, based on the value select in another select widget. Typical country - cities example. When user select country in first select widget, cities changed in the 2nd one, both. Are on the same page.

I am using version 6.2. Community, I am New to bonita with limited java knowledge.

Thank you for your support as this point is blocking me from demo first process to my company executives.

Kind Regards,
