First of all, I think you want the "Make Invoice" tab to list your PO
items, not your (already made) invoice items. So you want to display
data from the "po_item" table, not from the "invoice_item" table, which
only contains invoices you've already created.

For letting the user select a purchase order number from the dropdown
and then show all items of that purchase order, you can do something
very similar to the customer search field you've made: create a field in
an unbound block, link the dropdown to that unbound field, and in the
POST-CHANGE trigger, set the filter for the block displayed in the grid.

A hint on your data design: usually, purchase orders and invoices are
done with (at least) 2 tables: one table e.g. "invoice" containing data
valid for the whole invoice, like customer reference, invoice date,
invoice number, etc, and "invoice_item" containing a record for each
item on the invoice. This is a typical master-detail relationship.

Hope this helps you move forward.
