I want a portal that shows all the contacts.
If you click a contact I want to see a portal of all their invoices.
How Can i Do this?
Would the relationship be Contact ID to CONTACT ID Foreign key?

I think i'd approach it something like this:
1. when you click a portal row, it sets a global field in the current table (or a connected table) with that `Contact ID`. E.g. your global might be `MyTable::SelectedContactID`
2. then you have a relationship like `MyTable::SelectedContactID = InvoiceSelected::CONTACT ID Foreign Key`. Base your invoices portal on that "InvoicesSelected" table occurrence.
So every time you select a row, it changes the selected id and refreshing the Invoices portal will show only those for the selected contact.

Alternatively, if you base your current layout on `Contacts`, then you can use "Current Table" for your contacts portal, and a regular relationship to your related invoices in the layout body (`Contact::id --< Invoice::id_Contact`).
