Hello!

You can retrieve the values from a especific key or in a loop:
 

myMap.get(key).get(index).Field_1__c


or
 

for(Id forId : myMap.keySet()){
	for(customObject co : myMap.get(forId).values()){
		// co.Field_1__c ...
        // co.Field_2__c ...
	}
}
 


More information you can get in this link:

Hi Nandhini ,

let say we have dummymap

map<id,List<Dummy__c>> = new dummymap<id,List<Dummy__c>>();

Let say we want to take value of dummyfield__c from Dummy__c

for(id id:dummymap.keyset()){
    string fieldvalue = dummymap.get(id).dummyfield__c;
}

Hope it helps , else paste your code
