format changes when I use text flow to create flexible forms

First off, I hope I`m making sense in english:

I am using Adobe Experience Manager (Designer) to create forms. I want a textfield to expand when the text turns out to be longer than expected. Everything coming after that textbox is supposed to move down. I made that work in theory using "Teilformulare" or partial forms (I don't know if that is the correct translation). But the moment I change the setting from position to text flow, which will then allow the change in the pdf, everything jumps to the left and up. How can I keep my format and still be able to have the text-box expand with the entire form. I don't want the scroll funktion, because then I can save but not properly print the data. I've used several partial froms and some of the format within those partial forms stays in tact. However, all indidviual partial forms make that jump in the end.

Is there a different way to make the form expand or is there a way to keep my format using this method?

Best,

Nina
