I have a simple query that lists order history, one record for each Order Detail. I want to group all the same customer orders with a '+' (that acts as a dropdown) so that it will shorten the list and make it easier to view. In the above example All those records would combine into one and clicking on the + will expand the list. I know access does a similar thing when you have a sub table such as order details. All the Details are combined under one under number with a +.
