Hi, 
 

I am completely new to developing and im trying to create a custom quote for the company i work at.

I managed to find code i could use to display the related opportunity line items but for it displays the line item with the opportunity name before it.



Below is the code

public class CreateQuoteClass {    
public String opportunitystringId {get;set;}
public List<Opportunity> opportunityList {get;set;}
public List<quotewrapper> quotewrapperlist {get;set;}
public List<OpportunityLineItem> oliList{get;set;}
    
    public class quotewrapper
    {
        public Boolean isChecked {get;set;}
        public OpportunityLineItem oliresult {get;set;}
        
        public quotewrapper(Boolean isChecked, OpportunityLineItem oliresult)
        {
            This.isChecked = isChecked;
            This.oliresult = oliresult;
        } 
    }   
    
    public CreateQuoteClass(ApexPages.StandardController controller)
    {
        try{
            quotewrapperlist = new List<quotewrapper>();
            opportunitystringId  = ApexPages.CurrentPage().getparameters().get('Id');
            
            if(opportunitystringId!=null)
            {
                opportunityList = [SELECT Id,Name,CloseDate,AccountId,Pricebook2Id from Opportunity WHERE Id =:opportunitystringId];
                oliList = [Select Id,Name,Quantity,OpportunityId,UnitPrice,Product2Id,PricebookentryId,TotalPrice from OpportunityLineItem WHERE OpportunityId =:opportunitystringId];
            }
            
            if(oliList.size()>0)
            {
                for(OpportunityLineItem olObj:oliList)
                {
                    quotewrapper qobj =  new quotewrapper(false, olObj);
                    quotewrapperlist.add(qobj);
                }
            }
        }
        catch(Exception e)
        {
            System.debug('The following exception has occurred: ' + e.getMessage());
        }
        
    }
    

}
