It used to be possible, but LD withdraw this feature as apparently they couldn't get acceptable performance. Sad and much missed
I believe you also will only get 2 lines (default) unless you set the "minimum lines" property of the field as well.
It is a pitty it is discontinued
Are there any alternatives for this?
I was thinking, having a checkbox and a free text field attribute next to it. When the checkbox is ticked, another checkbox and free text field attribute appears underneath.
Always when the last checkbox is ticked, another checkbox + free text field appear.
Does that make sense?
Any further questions please let me know.
No alternatives at all within the product. You could do what you suggest, but then you will end up with lots of attributes that will need to be dealt with.
I'd suggest trying with a default size of (say) 10 lines and use the scroll bar. If users will accept that, then you don't have to do anything special.
