    Hi,

    Dependent picklists in Salesforce are very useful. They are used to limit the list of values in one picklist based on the value of another picklist.

    An example would be if you had a list of countries and states/provinces . If you select a country you would want the list of states/provinces to be filtered in the next picklist.

    Visualforce page

    <apex:page controller="DependentPicklistExpClass">
        <apex:form>
            <apex:pageblock>
                <apex:pageblocksection columns="2">
                    <apex:pageblocksectionitem>
                        <apex:outputlabel value="Country">
                        </apex:outputlabel>
                    </apex:pageblocksectionitem>
                    <apex:pageblocksectionitem>
                        <apex:selectlist size="1" value="{!country}">
                            <apex:selectoptions value="{!countries}"></apex:selectoptions>
                            <apex:actionsupport event="onchange" rerender="a"></apex:actionsupport>
                        </apex:selectlist>
                    </apex:pageblocksectionitem>
                    <apex:pageblocksectionitem>
                        <apex:outputlabel value="State"></apex:outputlabel>
                    </apex:pageblocksectionitem>
                    <apex:pageblocksectionitem>
                        <apex:selectlist size="1" value="{!state}" id="a">
                            <apex:selectoptions value="{!states}"></apex:selectoptions>
                        </apex:selectlist>

            options.add(new SelectOption('IN','India'));
            return options;
        }
        public list getStates()

            list options=new list();
            if(country=='US')

                options.add(new SelectOption('UK','Uttarakhand'));
            }

    Hi,

    The Dependent Picklist Field type is a special type of single-select picklist that displays different available values depending on the current selection in another (main) picklist.

    Hi Manpreet,

    A dependent picklist is a custom or multi-select picklist for which the valid values depend on the value of another field, called the controlling field. Controlling fields can be any picklist or checkbox field on the same record.

    A Dependent picklist helps the user in adding consistent and accurate data. The valid values in dependent picklist are generally dependable on values of other fields and this is called the Controlling field. The controlling field could be any picklist not more than 300 values on the same record. The other name for the dependent picklist is the custom picklist that can be defined for Opportunities whose valid values will surely depend on some other field.
