In Dialog dynamic dropdown for multiple generic list in acs common

[Ronnie09]

I have two dropdown
1st dropdown - Alpha, Beta, Gamma as a dropdown option in dialog.

2nd drop drown - Dynamically populating using generic list
if Alpha in 1st dropdown is chosen then ACS Common generic list (/etc/acs-commons/lists/alpha-list) data should be shown in drop down
if Beta is chosen then ACS Common generic list (/etc/acs-commons/lists/beta-list) data should be shown in drop down

Similarly if Gamma is chosen then ACS Common generic list (/etc/acs-commons/lists/gamma-list) data should be shown in drop down How can I achieve this.

I have followed below url and extracting single generic list using servlet and data population is working fine but confused about how to proceed for the above scenario

Please go through these links which explain and mostly achieve your requirements:
