I have three node types: Batch, Item and Order.
Batch and Order both reference Item through field_items.
I have a view which displays details of Items and the Order they relate to by Batch.
Not all Items will be linked to Orders, as Items may be allocated a few days after the Order has been received.
How can I add a field to this view which will allow me to link unallocated Items to an order?
Ideally, this field would be a dropdown/searchable text box in place of the Order number where I could choose the title/number of the order to link that Item to?
