Create Expandable Text Field Forms
Adobe Acrobat Pro needs to have the ability to create expandable text field forms that allow the text box to expand when the user types similar to what you can do with Livecycle.
This is a feature that has been requested a lot online. Currently Acrobat Pro only allows multi-line text field forms with a scroll bar, but you cannot create an expanding text field form that increases in the height of the text field to accomodate more text.
The functionality to create this even in Livecycle is too clunky and complicated to use.

@Anonymous: It is possible in Acroforms, a bit messy, and with some restrictions. Feel free to get in touch with me in private.

Hi,
I am working as fleet manager in a shipping company. I tried making pdf form with expandable text field. unfortunately it does not happen as there are no options available. the only option that i see is multi line and scroll bar. But no option for expandable text field. -

It is possible to build growing (unfortunately not shrinking) text fields in PDF forms. It is, however, quite clunky, and (in the opinion of the one who has developed this feature) a bit experimental.
The main reason for this is that the trigger for the overflow indicator in the text field is not accessible using Acrobat JavaScript. I have requested this several times in the past, but it has been refused with more or less weak arguments…

It is very late that I get to this thread, agreed.
But resizable "text boxes inside Comment App" ARE NOT WHAT THE OP REQUESTS!!
The OP (and many others, over all the years) request TEXT FIELDS to grow and shrink depending on their contents.
