Create Multigroups in Drupal 7 using Field Collections
One of my favourite things lately in Drupal 6 has been CCK 3, and more specifically, the Content Multigroups sub-module. Basically this allows you to create a fieldset of various CCK fields, and then repeat that multiple times. For example, I use it on this site whist creating invoices for clients. I have a fieldset called 'Line Item', containing 'Description', 'Quantity' and 'Price' fields. With a standard fieldset, I could only have one instance of each field - however, using a multigroup, I can create multiple groups of line items which I then use within the invoice.
