Button to add rows in interactive PDF Form

[default9bqcsaevq58a]

Hi, 

Ive been asked to create a table, where clients will be able to fill in information on an interactive PDF, with an "ADD" button to add more rows to the table.

I know this is possible, but how would i go about doing this? Is this something that needs to be done first in indesign before saving as an interactive PDF? If so could someoone help guide me as the best way to do this.

Im also worried about the flow of the content after adding rows, is there a way to help the content 'flow' if adding rows to the table.

An example of what i need to create is seen on PG3 of the attached PDF

This is not a built-in feature of a normal PDF file. The file you attached was created using a different application, called Adobe LiveCycle Designer, not with Acrobat.

This type of file is not really a PDF file, but an XML file with a PDF "envelope" around it. However, if the table you want to add is located on its own page and there's nothing after it that needs to be "pushed down" when new rows are added or removed then it can be achieved in a regular PDF form, but it requires quite a bit of scripting know-how.
