Custom line spacing in a fillable text form field

I figured it out, this can not be done in indesign which is something they need to work on because it defeats the idea of making a nice designed interactive pdf form.

In Acrobat

1. Choose Prepare Form > Select the text field and right click > Select Properties
2. Select "Options" tab and make sure Multi-Line and Allow Rich Text Formatting is selected > Close this window
3. Exit out of Prepare Form mode
4. Add some text in the text field > Highlight it and press CTRL + e > this will open up text field properties > select more... now you can edit your paragraph spacing.

NOTE: The only thing I noticed is that the text field might not hold onto those properties if the text is deleted, it seems to have reverted back to the default spacing.

2nd option, make multiple text boxes and link them together, again this can not be done in indesign and only done in Acrobat

1. Make multiple text boxes and name them properly. Example Text_1, Text_2, Text_#, etc
2. Right click on the first text box and open properties menu
3. In the "Options Tab" ensure "Scroll long text" is turned off
4. Next open up the format tab > Select Format Category : Custom > and open up the Custome Keystroke Script: by selecting "edit"
5. Enter this java script

if (event.willCommit || event.fieldFull) {

    this.getField("Text_2").setFocus();

}

Do this for all text boxes and make sure to write the name of next text field into the java script. This will tell the text fields that when one is full, to carry onto the next text field assigned.
