I have two dropdowns on my page and they are dependent. Main dropdown shows list of Groups. The dependent shows SubGroups for selected groupcode.
I have a method getGroupInfo and it returns a map. inside my getGroupInfo I populate the map like this ...
map.put(groupcode,results) ---results is a list of subGroup objects
I am getting all the GroupInfo values when the page is called using session object. How can I change the values in subGroup dropdown based on the groupcode chosen? I am not sure how to manipulate the "results" on groups dropdown change event?
This is referred to as "dependent dropdowns" or "dependent selects". It has been discussed recently in this forum in this thread. In addition, you will find a lot of information by "Googling" this topic.
