Seeking the Holy Grail of Drag and Drop

Need help
1

Please help if you can, I am stuck on a feature that is essential for my app and I think it’s a key feature a lot of apps would benefit from.

I have built a solid core of a project tracking system, and here’s the holy grail I am missing:

I need users to be able to order items in a repeating group. For instance, I need to easily be able to drag items to where they are wanted in the list (RG) with other items keeping their relative position.

As an example, if a list is in this sequence:
Apple
Banana
Cherry
Rhubarb
Strawberry

and I drag Rhubarb over Banana, the sequence should become this:
Apple
Rhubarb
Banana
Cherry
Strawberry

In a lengthy topic discussion (link to follow), The example showed how to implement a drag-drop where the dragged item trades places with the one it’s dropped on. I have made that work.

Later in the discussion, a question is raised about doing what I need. The answer baffled me. I am unable to figure out what it means and how to implement what I need.

Here’s the answer that has me stumped:

Here’s the top of the discussion:

I don’t understand how to use groups to retrieve values (the relative position of the cell’s content) of any cell other than the one that was dragged and the one dropped on. I also need a value from the cell below the one dropped on.

Is there a tutorial I should study that talks about how to refer to specific cells in a RG?

Is there something else I should know that is implied by “use groups to retrieve …”?

I have finally solved this. The plugin will be available in a day or two. You can even sort between multiple lists… its got nothing to do with moveit, im pointing out the gif in the last post.

The animation looks like exactly what I and other people need. Please let me know when it’s ready for me to test.
Thanks.
