We have a requirement wherein a portlet filter should display values based on another filters value selected by the end user.
So for example for a Region - USA i have various cities - New York, Dallas etc and for Region - India you have various cities like Delhi, Hyderbad etc.
if I select value "USA" for a Region filter on the portlet then its related values - New York, Dallas etc should be shown for me to be able to select on another filter- Cities.
Is there a way this can be done?
It can be easily done by using tokens.
