Index out of range when an item contain more children than other items

[MrFahrenheit-55]

When adding a 2nd-level child to one of the list items, the lowest-level item cannot be moved to another 1st-level child. This causes an error of index out of range for the parent item to which the item is being moved.

• To replicate, add a 2nd-level child to one of the DragDropItems.
• Run the application.
• Try to move the 2nd-level child to another 1st-level child.
• The program will crash with an error.

@PhilipNell-258 did you solve this issue?

@urmamb No, sorry. I decided to write my own widget.

@PhilipNell-258 would you be able to share the code of the widget you wrote, will save me a great amount of time. Nevermind if it's closed source, just trying my luck.

@8baba I have modified it way too much to tailor my app specific needs to be able to give you the exact code, but this issue can be solved with LLMs pretty easily.
