Fillable form text fields question ...

Hello,

  I am making a fillable form in ID CS6. I am using the "Buttons & Forms" pallete to make a text field that is fillable in a pdf when i export it. I can get that to work

My questions is, can i define the number of lines that are fillable in acrobat like a parapraph area?? When i start typing in acrobat, and hit enter, nothing happens. I can only get 1 line of text even if i make the text box huge in indesign. Trying to let someone type a paragraph in a set space of the form

Thanks in advance!
