Hi, is there any way to enumerated items?

For example

Picture a - 1  
Picture b - 2  
Picture c - 3

but if user re arrange item, the app must enumerate again like

Pic c - 1  
Pic a - 2  
Pic b - 3

Not sure exactly how a user in your app will be able to rearrange items, but yes, you can add a dynamic index to each item using this trick:

This will give you an array of RowIDs Use the Find Element Index column to find the index of the RowID in the array of RowIDs Use that in a template column to assign the ID to each dog. Here is what that might look like: Note that array indexes are zero based. If you w…

Thanks Robert, the idea is that the user uploads a few pictures, every picture would have a number like 1,2,3 just for an internal arrangement/order. But if the user wants that the picture number 3 be the picture number 1, he must drag the pictures and the app would change the order or I have to put a sort of number textbox in order to let the user assign the arrangement/order.  
I dont know wich term used for this, but note that for me arrangement is order, order of the list not a purcharse order.

@Rimatcom

It seems the RowIndex column and PhotoIndex column in the table would be independent of each other.

- PhotoIndex will be defined by your user when they re-arrange.
- RowIndex you can set up [as explained here](https://community.glideapps.com/t/rowid-is-great-could-really-use-row-number/16834/13).
