Field Sets

A field set is a grouping of fields. For example, you could have a field set that contains fields describing a user's first name, middle name, last name, and business title. Field sets can be referenced on Visualforce pages dynamically. If the page is added to a managed package, administrators can add, remove, or reorder fields in a field set to modify the fields presented on the Visualforce page without modifying any code.

Step 1: Create Field set in Account Object.

Setup->Customize->Account->Field Sets
Drag and Drop the fields required for the Field Set

Step 2: Create Visual Force Page

 <apex:repeat value="{!lstAccount}" var="acc"> 
 <table width="100%">
   <apex:repeat value="{!$ObjectType.Account.FieldSets.Account_FieldSet}" var="fieldSet"> 
     <tr> 
      <td>
        {!fieldSet.Label}
      </td>   
      <td>
       <apex:inputField value="{!acc[fieldSet]}"/>
      </td>
      </tr>   
       </apex:repeat>
      </table>
</apex:repeat>

Step 3: Write the Controller for the VisualForce Page

public with sharing class DynamicTabController 
{
    public List<Account> lstAccount{get;set;}
    
    public DynamicTabController()
    {
        lstAccount=new List<Account>();

                String query = 'SELECT ';
                for(Schema.FieldSetMember f : this.getFields()) 
                {
                    query += f.getFieldPath() + ', ';
                }
                query += '  Id FROM Account limit 5 ';
                System.debug('query ------>'+query );
                lstAccount = Database.query(query);        
    }

    public List<Schema.FieldSetMember> getFields() 
    {
        return SObjectType.Account.FieldSets.Account_FieldSet.getFields();
    }
}
