Is it possible to randomly insert a row in a portal at any point, including between two populated rows?

For example, I am working on a recipe database and have created a one to many relationship between the ingredients used in a recipe and ingredients (inventory ultimately).

Let's say I have all of my ingredients entered and I discover I forgot to enter something and I want to enter the new ingredient between two other populated rows. I would like to create a button to insert a new row above the row the cursur is current located. Is this possible?

Also, can I physically drag and drop a row to a different order in the portal? 

Thank you,

You'll need to have a (number) field to sort on, and apply the sort to your portal or its relationship.
Your "insert" script would then take the active row's sortField and e.g. subtract .5 and etc.

It's possible to achieve this effect using drag and drop via script triggers. There are a couple of demos floating around... here's one.

Might be a lot to bite off if you're new, but you'll have to be the judge. Welcome to the forums.

Fitch, 

Ah, yes, I think I am in this project way more than I would like, but...

Is the number field placed on the portal line? Will I have the field auto-enter a value? 

How do I "apply the sort" to the portal?

Thank you for your patience and assistance!

The field would be in the related table. You'd need it in the portal if you want to manually edit it. Otherwise it doesn't have to displayed.

Go to layout mode and double-click the portal to see its options (of which Sort is one).
