Hi,

I want to edit opportunity record and its related child record at the same page in vf; once I check the opportunity it should show its related child record and allow me to make changes to both opportunity and child record. Currently I can do it on two separate pages. below are the current lines of the code for apex and vf.. also, I should be able to manage the colums properly on my page so that i dont need to scroll the page..Please assist..

public class wrapperListOpportunity
{
    public list<wrapperOpp> wrappOppList{get;set;}
    public list<Opportunity> getOppList = new list<Opportunity>();
    public list<Order_Intake_Forecast__c> oifList{get;set;}
    Public list<Order_Intake_Forecast__c > oilist{get;set;}
    Public list<opportunity> oplist{get;set;}
    public boolean selectedCheck{get;set;}
    public String strDQIDueDays{get;set;}

    public List<SelectOption> getDQIDueDays(){
        Schema.DescribeFieldResult F =  Opportunity.DQI_Due_In_Days__c.getDescribe();
        List<Schema.PicklistEntry> P = F.getPicklistValues();
        List<SelectOption> options = new List<SelectOption>();
        //options.add(new SelectOption('','--All--'));
        for(Integer i = 0; i < P.size(); i++){
            options.add(new SelectOption(P[i].getValue(), P[i].getLabel()));
        }
        return options;
    }

    {   selectedCheck = false;
