I am using SharePoint 2016 and InfoPath 2013. I am using Multline textboxes . When users are filling the text the multiline text box goes down with white space as shown in fig below. I tried to make it "Expand to show all text" but no use. When I keep "Automatically expand while typing" option its giving me problems while choosing printing the form. Can some one suggest what should be done to avoid that white space which I am getting.
I have had similar issues when I've tried to use multiline text boxes, so I try and avoid them. I've been able to resolve my format issues by switching the text boxes to rich text boxes rather than multiline ones. With rich text boxes you can wrap the text which helps alleviate a lot of the formatting issues that multiline boxes develop.
Before adding text to the rich text box set to expand to show all text:
Make sure your text box is not inside a section or something that would cause that field to expand as your text box expands.
