Hello, 

I have a controller that I use to dynamically group opportunities by a picklist field and display them on a VF page, and I would like to add the ability for my users to edit the opportunities from the page but I am having trouble getting it all to fit together. Can anyone help?

Here is my controller: 
 

public with sharing class QualOpController
{

public List <Opportunity> Opty {get;set;}
public list<String> campaigns {get;set;}

public PageReference saveOp(){
    UPDATE Opty;
    return null;
    }

 public String getName(){
        return 'QualOpController';
        }

public void load() 
{
  campaigns= new List<String>();
  Opty = [Select id, name, CreatedDate, StageName, Vert_Med__c, Company_Name__c, Next_Step__c, Vertical__c, Weeks_Live__c, Days_Since_Last_Modified__c, Contract_SENT__c, NextStep, LeadSource, Probability, Spend_Last_Week__c, Spend_Last_30_Days__c, Owner_Name__c, Revenue_All_Time__c from Opportunity WHERE Pipeline_Oppty__c = TRUE ]; 
  
  Set<String> campaignSet = new Set<String>();
  for (Opportunity j : Opty)
      campaignSet.add(j.Vert_Med__c);
      
      for (String campaign : campaignSet) 
      {
            campaigns.add(campaign);
      }
      campaigns.sort();
    }
}

I think it has something to do with my variable being a string?

Here is the pageblock where I am displaying the data:

<apex:repeat value="{!campaigns}" var="camp">

    <apex:form >
    <apex:pageBlock title="{!camp}" mode="inlineedit">

                     <apex:commandButton action="{!saveOp}" value="Update Opptys"/>  
    </apex:pageBlock>
    </apex:form>
            <br/>
  </apex:repeat>

Is there any hope for me??

Thanks in advance!
