Hello,
I have one autoincrement column: RowID
I would like to have another columns, InputRowIDs that can only be filled in by existing ROWIDs, and I would like these to be placed in a Drop down menu.
Is this possible? The output table would look like the table below. Everything in InputRowIDs should come from a dropdown menu
Example
```
PK :: RowID | InputRowIDs
0. :::: 0 | NULL
1. :::: 1 | 0
2 :::: 2. | 0
3 :::: 3 | 1, 2
4 :::: 4. | 3
```
