Hi Amita,

Can you use the selectoption instead of inputfields.
with the help of selectoptions you can capture the selected value and send to controller with the help of action Support.
If you want to rendered the page so create boolean variable in apex and use that on vf page for rendering.

Thanks
Shivdeep

Hi Amita,

Please try the below code, it's just a sample so update it with your requirement.
Class::

public with sharing class SurveyClass{

Public Account acc{get;set;}
Public Proposal_Form__c pfc {get;set;}
Public ID rid;
public string SFselectedValue {get;set;}
public string SCselectedValue {get;set;}

private ApexPages.StandardController standardController;
    
public SurveyClass(ApexPages.StandardController controller) {
    this.standardController = standardController;
    acc = (Account)controller.getRecord();
  }

  public List<selectoption> getServiceFamilyValue() {
List< selectOption> SFOptions = new list<selectOption>();
for(Proposal_Form__c p :[select Service_Family__c from Proposal_Form__c]){ // Replace serviceFamily with your field API name
SFOptions.add(new selectOption(p.Service_Family__c,p.Service_Family__c)); // Replace serviceFamily with your field API name
}
return SFOptions;
}
public List<selectoption> getServiceCategoryValue() {
List< selectOption> SCOPtions = new list<selectOption>();
for(Proposal_Form__c p :[select Sub_Service_Category__c from Proposal_Form__c]){ // Replace servicecategory with your field API name
SCOPtions.add(new selectOption(p.Sub_Service_Category__c,p.Sub_Service_Category__c)); // Replace servicecategory with your field API name
}
return SCOPtions;
}
public void Selected(){
//acc = [SELECT Id, Name, Proposal_Form__r.Name, Proposal_Form__r.Fields_Associated__c, Proposal_Form__r.Service_Family__c, Proposal_Form__r.Sub_Service_Category__c FROM Account ];
pfc = [SELECT Fields_Associated__c FROM Proposal_Form__c where Service_Family__c =: SFselectedValue and Sub_Service_Category__c =: SCselectedValue];
System.debug('#####pfc '+pfc);
