Something like the following is how you would join the table to itself(with assumptions from what you have provided). You would need to alias each copy so you know if you are talking about the brand or a different attribute row of the table.

Select b.Product, b.value [Attributename1], g.Attributename, g.value 
  from myItemTable b 
  join myItemTable g ON g.id = b.id 
 Where b.Attributename = 'Brand'
   and g.Attributename = 'Enable / Disable'
