View with a record summary and below a list of records linked to the one on top

How can I create a view that shows a record summary on top  and a list of various records linked to the one on top.
 
Say, we have a sales order with client, date, etc.. on top. We want this info on top of the view for the selected record. Then another form (sold items) holds products sold and are linked to their sales orde, i.e. the sold item record have a look up field linking to the sales order.
 
I want to see the sales order details on top and a list of sold items linked to that sales order below.
 
How can I do this??
 
This goes for other examples like a work order with daily progress reports below or sales leads with comments below, etc... I hope I explained myself and what I want makes sense... Appretiate your help.
