Hey @LeandroHBayer,

There is no formula for that. The only way in which you can play around with that is by adjusting:
1. Row Height -as shown on image below.
2. Field width -dragging just as you would on google sheets.

If tor the Row Height you choose "Extra Tall", it is more probable that you will get the "vertical orientation".

Let me know if that worked.

Actually, you could use a formula within a rollup to vertically stack the values.
Try the following:
Create rollup of Name Field form Role (ph), and include this formula for the rollup.

That will apply line breaks to your array. See dummy example on image below.

Best,
Mike
