Connecting text fields/lines in PDF Form

[defaultyiugfq1zd7ed]

I joined two text boxes ("A", "B") lines using:  if (event.fieldFull){getField("B").setFocus();} which works better but when I try to edit/delete/modify the texts in the first text box("A"), I can't easily edit it as I have to delete some part of the text then enter the new text instead of pushing the rest of the texts to the next lines. Is there any help regarding this here in the community?

Actually I wanted to correct heading but didn't know editing the post so did it.
