We have working editable detail grid, now we have added an "Unlimited length text field" into it. How we can configure this field to make it Multi line field in Editable Detail Grid just like its behavior in edit page.
I remember reading a post or Academy page about it but I have not tried it yet, myself. I want to know how to do this as well. I think they said you can apply custom CSS. Maybe this link can get you in the right direction. Let me know if you succeed.
