Do you mean by a dropdown a many2one field in an Odoo/openERP view ?
create a calculated field in the res.partner table that holds the count of the sales order created for this customer, name it 'sale_count'. Make this field searchable.
in the many2one field that shows the customers add a domain filter as
domain = [('sale_count','>',0)]
I hope this works
