I am currently trying to set placeholder text for cells created using dynamic columns so that when their value is null, the text "Enter Value" will appear. But add-ons are unavailable on Dynamic Columns. The placeholder allows users to click on it and input a value. However, if I set the initial value of a cell as null in the dynamic column cells, nothing appears for the user to click and edit. The issue is resolved if I input an initial valid value, but I prefer the value to start as null. Is there a workaround for this? If not, it would be a great feature to have!
Hi @Natan_W

Not currently, but I put in a feature request. I'll let you know if this change rolls out!
