How to create associated multiple drop down list widget

I have a requirement where I need to display a list of value in a drop down menu and once i select any value from this drop down associated values should be populated in another drop down. for example Drop down one will display list countries and drop down two will show only the list of States of that particular country. Any suggestion how to achieve this?

Hi Dilip, 

  1. Create an 1-* association between the entities country and state. 
  2. Use two reference selectors, One for selecting country and another for state 
  3. In the onChange event of country have a microflow that refreshes the objects changes in client
  4. Now, In the selctable objects of the state reference selector retreive and provide the values related to the country selected which can be given as input parameter for the selectable objects microflow.
