One not bad option I have been playing around with is to add an empty invisible group or (if you’re using Layouts) invisible container that essentially “props up” the text input when it is selected so that it floats just above the keyboard.
Here is a small demo app. Container 3 is set to invisible and has a fixed height of 100px. When I click on the text input, Container 3 is then set to visible.
