Hello,

I followed blog below to display two dependent picklist
https://www.sundoginteractive.com/sunblog/posts/displaying-dependent-picklist-fields-on-a-visualforce-page

public with sharing class locationController{
 
    public list<location__c> locationList{get;set;}
 
    public locationController(){
        locationList = [Select ID, Country__c, State__c, City__c
                From Location__c];
    }
     
}



<apex:page controller="locationController"> 
  Location Table
  <apex:messages style="color:red"></apex:messages>
   
    <apex:form>
        <apex:pageblock>
            <apex:pageblocktable value="{!locationList}" var="locItem">
                <apex:column headervalue="Country">
                    <apex:inputfield value="{!locItem.Country__c}">
                     </apex:inputfield>
               </apex:column>
             
              <apex:column headervalue="State/Province">
                    <apex:inputfield value="{!locItem.State__c}">
                    </apex:inputfield>
               </apex:column>
             
              <apex:column headervalue="City">
                    <apex:inputfield value="{!locItem.City__c}">
                    </apex:inputfield>
               </apex:column>
            </apex:pageblocktable>
        </apex:pageblock>
    </apex:form>
   
</apex:page>

How can this example be modified to use "pageBlockSection",  or is there any better way to display picklist and dependent picklist like a pageBlockSection fashion.

I have two standard objects, Order and Contact. I have created a Contact lookup (API- Contact_Lookup__c) in Order and included its related  list in the page layout of Contact.

But when I enter a new record in Contact, then go to related list to add an order to it, hit save, the new Order record gets inserted in the Order records but it does not get displayed in the related list on contact detail page for that record.

Please help
