Dynamic Radio buttons on Visualforce

Hello All, 

I have a requirement where I need to present a Master detail objects in the form of a question(master) and radio button options (detail)

Example:

1. What is the Capital of USA
  • Washington DC
  • Newyork
2. What is the Capital of India
  • New Delhi
  • Mumbai
  • Hyderabad
  • Bangalore
  • Chennai
3. What color is a Rose
  • Red
  • Pink
  • Yellow

Here the Master record is the Question and the Child options are the detail records.

I have achieved half of it, but I am finding difficulty associating the detail records to their respective masters on the VF page

Here is the code 
  
<apex:page standardController="EFL_Inspection_Questionnaire__c" extensions="CARPOL_inspection_questionnaire" showHeader="true" >
  <h1>This is how the Questionnaire is going to look</h1>
  <apex:form >
  <apex:repeat value="{!qs}" var="q" id="theRepeat">
        <apex:outputText value="{!q.Question__c}" id="question"/><br/>
        <apex:selectRadio value="{!country}">
            <apex:selectOptions value="{!items}"/>
        </apex:selectRadio>
        <apex:inputField value="{!q.Comments__c}" style="width: 400px; height: 40px" id="comments"/><br/><br/><br/>
    </apex:repeat>
    
    

</apex:form>
</apex:page>



**********************************************controller*************************************

public class CARPOL_inspection_questionnaire {
    String country = null;
    List<EFL_Inspection_Questionnaire_Questions__c> questionnairequestions = new List<EFL_Inspection_Questionnaire_Questions__c>();
    Id questionnaireid;
    public CARPOL_inspection_questionnaire(ApexPages.StandardController controller) {
    questionnaireid = ApexPages.currentPage().getParameters().get('id');
    }
    
    public List<EFL_Inspection_Questionnaire_Questions__c> getqs() {
       questionnairequestions= [SELECT ID,NAME,Question__c,Comments__c,Answer__c FROM EFL_Inspection_Questionnaire_Questions__c WHERE EFL_Inspection_Questionnaire__c=:questionnaireid];
        return questionnairequestions;
    }
    
    public List<SelectOption> getItems() {
        List<SelectOption> options = new List<SelectOption>();
        
        List< EFL_Inspection_Questionnaire_Responses__c > responseoptions = new List< EFL_Inspection_Questionnaire_Responses__c >();
        responseoptions = [SELECT ID,NAme, EFL_Inspection_Questionnaire_Questions__c, Response__c FROM EFL_Inspection_Questionnaire_Responses__c WHERE EFL_Inspection_Questionnaire_Questions__c IN:questionnairequestions];
        
        for(EFL_Inspection_Questionnaire_Responses__c r:responseoptions){
            options.add(new SelectOption(r.Response__c,r.Response__c));
        }
        return options;
    }
    
    public String getCountry() {
        return country;
    }
                     
    public void setCountry(String country) { 
        this.country = country; 
    }
}




I would be grateful if anyone could help me out with this. 


Thanks a lot

Hi Nitish,

You need to crate the wrapper class to associate the options only specific to the question.
Please try the below code. 
<apex:page standardController="EFL_Inspection_Questionnaire__c" extensions="CARPOL_inspection_questionnaire" showHeader="true" >
  <h1>This is how the Questionnaire is going to look</h1>
  <apex:form >
  <apex:repeat value="{!qs}" var="q" id="theRepeat">
        <apex:outputText value="{!q.question}" id="question"/><br/>
        <apex:selectRadio value="{!q.selectedAnswer}">
            <apex:selectOptions value="{!q.ansOptions}"/>
        </apex:selectRadio>
        <apex:inputField value="{!q.Comments}" style="width: 400px; height: 40px" id="comments"/><br/><br/><br/>
    </apex:repeat>
    
    

</apex:form>
</apex:page>



**********************************************controller*************************************

public class CARPOL_inspection_questionnaire {
    String country = null;
    List<question> questionnairequestions = new List<question>();
    Id questionnaireid;
    public CARPOL_inspection_questionnaire(ApexPages.StandardController controller) {
    questionnaireid = ApexPages.currentPage().getParameters().get('id');
    }
    
    public List<question> getqs() {
		EFL_Inspection_Questionnaire__c lst = [SELECT ID,NAME,Question__c,Comments__c,Answer__c,(select id, Response__c from EFL_Inspection_Questionnaire_Responses__r) FROM EFL_Inspection_Questionnaire_Questions__c WHERE EFL_Inspection_Questionnaire__c=:questionnaireid];
        for(EFL_Inspection_Questionnaire__c q: lst){
				question qObj = new question(q.Question__c, q.EFL_Inspection_Questionnaire_Responses__r);
				questionnairequestions.add(qObj);
		}		 
        return questionnairequestions;
    }
    
    /*public List<SelectOption> getItems() {
        List<SelectOption> options = new List<SelectOption>();
        
        List< EFL_Inspection_Questionnaire_Responses__c > responseoptions = new List< EFL_Inspection_Questionnaire_Responses__c >();
        responseoptions = [SELECT ID,NAme, EFL_Inspection_Questionnaire_Questions__c, Response__c FROM EFL_Inspection_Questionnaire_Responses__c WHERE EFL_Inspection_Questionnaire_Questions__c IN:questionnairequestions];
        
        for(EFL_Inspection_Questionnaire_Responses__c r:responseoptions){
            options.add(new SelectOption(r.Response__c,r.Response__c));
        }
        return options;
    }*/
    
    /*public String getCountry() {
        return country;
    }
                     
    public void setCountry(String country) { 
        this.country = country; 
    }*/
	public class question(){
		String question{get;set;}
		List<selectOption> ansOptions{get;set;}
		String selectedAnswer{get;set;}
		String comments{get;set;}
		public question(String question, List<EFL_Inspection_Questionnaire_Responses__c> answers){
			this.question = question;
			List<selectOption> lstAns = new List<SelectOption>();
			for(EFL_Inspection_Questionnaire_Responses__c ans: answers){
					lstAns.add(new selectOption(ans.Response__c, ans.Response__c));
			}
			this.ansOptions = lstAns;
		}
	}
}
Hope this helps.

Thanks Anupama. 

I was actually missing the idea of tying the question and answer together on the VF page. This wrapper helped a lot. 
Really appreciate your help. 

Thanks
