Hey Veeraiah,

You can do it using SelectList. Whenever the User will click on Search Buttion, You will Query on object Where the the use will be of type the selected picklist field. Here you will get List<Custom_Object> records which will have questions & answers of the slected picklist type. Just show this list on VF page.


1) public List<String> selectedValue {get;set;}
public List<SelectOption> getUserType()
{
  List<SelectOption> options = new List<SelectOption>();
     
   Schema.DescribeFieldResult fieldResult =CustomObject__c.getUserType__c.getDescribe();
   List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
     
   for( Schema.PicklistEntry f : ple)
   {
      options.add(new SelectOption(f.getLabel(), f.getValue()));
   }    
   return options;
}

With our controller logic all complete, we can call the getUserType() method from our Visualforce page,  and populate the <apex:selectList> tag:

2) <apex:selectList id="countries" value="{selectedValue}"
         size="1" required="true">
  <apex:selectOptions value="{!countries}"/>
</apex:selectList>

3) You will query in that Custom object when the Search button will be click with selectedValue which will return of list of records. Now rerender the form or Outputpanel.

Let me know if you didn't understand the scenario or any query. Happy Coding!!!
