I was in a chat session the other day with them to see if this was resolved yet. They told me that i would have to pay someone to write a javascript thing to add into the "action" on my text field that i wanted to expand. mmmm, if they know that javascript will work (which i am not a programmer) then why can't Adobe just add that capability into the program. I was asked to submit my suggestion to their wishlist. Since there are lots of people on your forum who are already asking and wishing for it for years, why am i adding this to a wishlist??? :-)

I too am waiting........patiently, but years? Them saying they know this feature needs to be added and still not added? Why so long of a wait?

Why is this feature still not available in Adobe? Seriously guys... This should have been available years ago!!!

Still no feature addition with Adobe? I too bought Adobe Acrobat Pro thinking it could do this basic task. Does anyone have an alternative? Besides Experience Manager?

ABSOLUTELY need!

I would like to know alternates as well. If Adobe is unwilling to respond to anyone maybe it's time to move elsewhere.

I would love to know what alternates are out there too. I've looked at several but none of them have this ability.

Was actually looking for more info on the Experience Manager and the costs involved - asked twice to have someone contact me - with the understanding that the only reason I'm looking at this option is if it has the ability to do expanding text field forms. Never heard from anyone. :-)

Any suggestions on alternate software that might do this function.

I believe Adobe's goal is to have everyone migrate to Experience Manager Forms. It must be really expensive though, because I can't find pricing anywhere!

This has been requested now for years. ADOBE ... let us know if you're going to do this or not. Under review for over two years is unacceptable

ABSOLUTELY need!

I need this so bad... This feature is so necessary... please add it to acrobat dc.

absolutely dying for this feature! It's the only feature I'm missing to make super functional forms.

Absolutely essential that this feature be available in forms. Otherwise, we'll be forced to create such forms in Word, which has this capability.

We still NEED this feature!!!!!!!

Big time YES! It is actually laughable that this feature is not yet included in Acrobat!

Yes to adding this BASIC functionality!

This request has been on the docket for a long time. Years ago, I stopped using Acrobat because it lacked this feature. Switched to Word (c'mon Adobe, we really have to go there?!!). Luckily, the field of competitors grew substantially and there are some options. I decided to come back to Adobe to check things out before making a commitment. I am bummed that this won't work. It's not a hard feature to implement and it seems it's turning off new (or returning, like me) users quickly and sours the image of the brand. Please consider taking care of this asap. I'd like to stay with Adobe, but this feature is key.

I bought Adobe pro for this specific purpose only to find out it doesn’t have the capability. This is very upsetting for my company. I debated going with Adobe or another software program, and now I regret my decision. We will not be renewing. Now we’ll have to purchase from another company to fill this need. Such disappointment. You’ve absolutely fragmented your program availability to make more money and it’s sad. Glad there are so many competitors now. Lesson learned.

I need this for the form I am creating using the tools of Adobe Acrobat Pro 2017.

UPVOTING this issue.
